It took some puzzling to work out that the key part of that message was:
 +
can't find header files for ruby at /usr/lib/ruby/include/ruby.h
 +
...suggesting that the Ruby header files (presumably in the <code>ruby-dev</code> package) need to be installed.
 +
 +
Having installed them, we will try again...

Presumably we just need to install [[zlib]]... but searching for "zlib" in {{l/linux/cmd|apt}} came up with several packages:
 +
{|
 +
|-
 +
|zlib1g || compression library - runtime
 +
|-
 +
|zlib1g-dbg || compression library - development
 +
|-
 +
|zlib1g-dev || compression library - development
 +
|-
 +
|zlibc || An on-fly auto-uncompressing C library
 +
|-
 +
|zopfli || zlib (gzip, deflate) compatible compressor
 +
|}
 +
Our first guess was <code>zlib1g</code>, but that was already installed. Searching for the error came up with a post by someone who had solved it with <code>zlib1g-dev</code>, so we tried that next... and it appears to have succeeded:

===Redmine config===
 +
Looking through my main [[Redmine]] documentation, I saw mention of [[Redmine/rake]], and the <code>rake about</code> command which reports on what Rails frameworks are available. I figured that if nothing else, Rails needs to be available.
 +
<pre>
 +
root@cloud1:~# rake about
 +
rake aborted!
 +
No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb)
 +
 +
(See full trace by running task with --trace)
 +
</pre>
 +
Okay, so maybe we need to be in Redmine's project folder...
 +
<pre>
 +
root@cloud1:~# cd /home/vbzo/domains/rm.vbz.ovh/site/svn/redmine-4.1
 +
root@cloud1:/home/vbzo/domains/rm.vbz.ovh/site/svn/redmine-4.1# rake about
 +
Please configure your config/database.yml first
 +
Could not find gem 'rails (= 5.2.4.1)' in any of the gem sources listed in your Gemfile.
 +
Run `bundle install` to install missing gems.
 +
</pre>
 +
This feels a bit like skipping around arbitrarily, but maybe I should run <code>bundle install</code> at this point?
 +
 +
Part of the problem may be that I installed Rails 6, but Redmine is apparently configured to demand 5.2.4.1 and nothing else...
 +
<pre>
 +
root@cloud1:/home/vbzo/domains/rm.vbz.ovh/site/svn/redmine-4.1# bundle install
 +
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application for all non-root users on this machine.
 +

Bundle complete! 30 Gemfile dependencies, 81 gems now installed.
 +
Use `bundle info [gemname]` to see where a bundled gem is installed.
 +
Post-install message from i18n:
 +
 +
HEADS UP! i18n 1.1 changed fallbacks to exclude default locale.
 +
But that may break your application.
 +
 +
Please check your Rails app for 'config.i18n.fallbacks = true'.
 +
If you're using I18n (>= 1.1.0) and Rails (< 5.2.2), this should be
 +
'config.i18n.fallbacks = [I18n.default_locale]'.
 +
If not, fallbacks will be broken in your app by I18n 1.1.x.
 +
 +
For more info see:

I don't get why "installing your bundle as root will break this application for all non-root users on this machine", since as far as I can tell they're ''always'' installed as root-owned. The old install on cloud4, which was done with {{l/linux/cmd|apt}}, has <code>/var/lib/gems</code> and all its contents owned by root, so I think that's the way it's supposed to be. Maybe the [[Gemfile]] gets root-owned? That'll get taken care of later when I re-[[chown]] the Redmine project folder (before trying to run it).

===Redmine folder setup===
 +
Removing the original <code>public_html</code> folder because it's empty and I want to use Redmine's <code>public</code> folder for that. I could point Apache directly at {{arg|redmine folder}}<code>/public</code>, but when given a choice I'll do things where reconfiguration does ''not'' require restarting anything.

 +
It remains unclear where Redmine (especially the new one) expects config files to be.
 +
 +
On cloud4 (old installation), configuration files are in <code>/etc/redmine/default</code>, which is linked from the main project folder:
 +
<pre>/usr/share/redmine/instances/default/config</pre>
 +
is a link to
 +
<pre>/etc/redmine/default</pre> -- but where is it set that Redmine expects to see instance-configuration folders in {{arg|redmine-folder}}<code>/instances</code>? New Redmine doesn't have an instances folder.
 +
 +
Looking through the new install for anything that might be pointing at configuration files/folders, I found <code>appveyor.yml</code>, but that seems to be part of something called [[AppVeyor]] which is some kind of continuous-integration service (i.e. part of Redmine's development process) and not part of installing or running an instance.
 +
 +
Skipping around a bit -- when I try to access the instance, I get this error:
 +
 +
[[File:2020-02-12.screen.Forbidden error.png]]
 +
 +
This looked like an [[Apache web server|Apache]] error, so I checked Apache's error log and it seems to support this:
 +
<blockquote>[Wed Feb 12 20:18:22.406987 2020] [autoindex:error] [pid 28388] [client 107.15.53.219:5345] AH01276: Cannot serve directory /home/vbzo/domains/rm.vbz.ovh/public_html/: No matching DirectoryIndex (index.html,index.htm,index.php) found, and server-generated directory index forbidden by Options directive</blockquote>
 +
I had changed the <code>DirectoryIndex</code> (in Apache's config for this domain) to <code>dispatch.fcgi</code>, which evidence suggests is what Redmine uses for an index file, but the error suggests that Apache is still looking for index.* files.
 +
 +
I thought I had restarted Apache after making that change but apparently I hadn't, because restarting it resulted in a ''different'' error:
 +
 +
[[File:2020-02-12.screen.Internal Server Error.png]]
 +
 +
Looking for evidence of how Apache is supposed to be configured for .fcgi files... The new Redmine comes with a file called <code>htaccess.fcgi.example</code> which one presumes is supposed to be renamed [[Apache web server/.htaccess|.htaccess]] (or maybe <code>htaccess.fcgi</code>? and how would that get invoked?) but there are no instructions.
 +
 +
In any case, that file contains the code:
 +
<pre>
 +
<IfModule mod_fastcgi.c>
 +
    AddHandler fastcgi-script .fcgi
 +
</IfModule>
 +
<IfModule mod_fcgid.c>
 +
    AddHandler fcgid-script .fcgi
 +
</IfModule>
 +
</pre>
 +
Meanwhile, the site-config on cloud4 (old server) has this:
 +
<code>
 +
        Options +ExecCGI
 +
        AddHandler cgi-script .fcgi
 +
        DirectoryIndex dispatch.fcgi
 +
 +
        # RAILS-SPECIFIC STUFF
 +
       
 +
        RailsBaseURI /
 +
        PassengerUser vbz-net
 +
</code>
 +
I copied those lines into the site-config on cloud1 (new server), but Apache didn't like them. Investigation revealed that <code>RailsBaseURI</code> is the first problem -- presumably Rails directives aren't being recognized because Apache needs a Rails module enabled.
 +
 +
Disabling those two lines for now leaves us with this in the Apache error log:
 +
<blockquote>[Thu Feb 13 01:03:23.890549 2020] [cgi:error] [pid 5631] [client 107.15.53.219:55937] AH01215: Please configure your config/database.yml first: /home/vbzo/domains/rm.vbz.ovh/public_html/dispatch.fcgi</blockquote>
 +
This is at least a clue towards the "where should the config files go" question.
 +
 +
At that point I copied the two <code>.example</code> files to new names:
 +
* <code>configuration.yml.example</code> &rarr; <code>configuration.yml</code>
 +
* <code>database.yml.example</code> &rarr; <code>database.yml</code>
 +
I ''still'' don't know where they are ''supposed'' to go, but now maybe I have a test to see if they're in the right place? I've put the renamed copies in the same folder as the original example files.
 +
 +
==2020-02-13==
 +
===part 1===
 +
I'd imported the Redmine database earlier but not created a user for it; did that now, and configured <code>database.yml</code> with the appropriate credentials. I now get this error in Apache's log:
 +
<blockquote>

followed by what looks like an execution-stack trace.
 +
 +
I think this means I need to install the <code>mysql2</code> gem, which I think I might know how to do.
 +
===part 2===
 +
I'm testing a theory about why <code>gem</code> sometimes complains about being run as root, so I ran it as root:

 +

 +
Looking at mkmf.log, the key seems to be lines ending in "-------------------- {{arg|yes/no}}", where the first and only "no" line is:
 +
find_library: checking for -lmysqlclient... -------------------- no
 +
So presumably I need to install lmysqlclient. (From apt, I hope?)
 +
===part 3===
 +
[https://stackoverflow.com/questions/4198623/cannot-find-lmysqlclient This article] suggested that the package might be called <code>libmysqlclient-dev</code>, so I searched <code>apt</code> for "libmysql" and found <code>default-libmysqlclient-dev</code>, which I installed.
 +
 +
I then tried gem install again:
 +
<pre>
 +
root@cloud1:/home/vbzo/domains/rm.vbz.ovh/site/svn/redmine-4.1# gem install mysql2
 +
Building native extensions. This could take a while...

 +
...and all appears right with the world.
 +
===part 4a===
 +
Now what error do we get?
 +
<blockquote>[Thu Feb 13 19:19:58.871510 2020] [cgi:error] [pid 28015] [client 107.15.53.219:7649] AH01215: /var/lib/gems/2.5.0/gems/yard-0.9.24/lib/yard/config.rb:95:in `expand_path': couldn't find login name -- expanding `~' (ArgumentError): /home/vbzo/domains/rm.vbz.ovh/public_html/dispatch.fcgi</blockquote>
 +
===part 4b===
 +
Experimentation determined that Apache was not setting the <code>$HOME</code> environment variable, which was probably causing this failure. After some futzing around it finally dawned on me that this is probably what those two Rails-specific Apache directives --
 +
<pre>
 +
        # RAILS-SPECIFIC STUFF
 +
        RailsBaseURI /
 +
        PassengerUser vbzo
 +
</pre>
 +
-- which I had commented out -- were intended to remedy. It therefore was necessary to install whatever thing made it possible for Apache to recognize them, which turns out to be [[Phusion Passenger]].
 +
 +
False start: I initially tried installing them from <code>apt</code>, but this led to an error about [[bundler]] being too old (despite the bundler gem being of the needed version, 2.14, where the requirement was at least version 2.
 +
 +
After some further dead-end futzing around, I realized that installing Passenger from apt had probably brought in a bunch of outdated stuff including bundler, so all that needed to go away and Passenger needed to be [https://www.phusionpassenger.com/docs/advanced_guides/install_and_upgrade/standalone/install/oss/bionic.html installed from a current source]:
 +
* <code>dirmngr is already the newest version (2.2.4-1ubuntu1.2).</code>

I restarted Apache, but it didn't seem to make any difference; still getting the same error, although the form has changed slightly:

 +
</pre>
 +
I confirmed that the error means what I think it means by putting this line right before config.rb line 95:
 +
<source lang=ruby>system("echo HOME IS [$HOME]")</source>
 +
This returns <code>malformed header from script 'dispatch.fcgi': Bad header: HOME IS []</code> as expected.
 +
 +
Googling the ''current'' version of the error message, I found that someone had fixed the problem like this (forgot to save the link, but there's a more compact version [https://github.com/reidmv/reidmv-taskplan/blob/master/tasks/init.rb#L17 here]) - inserted before the debug line:
 +
<source lang=ruby># The HOME environment variable is important when invoking Bolt. If HOME is not
 +
# already set, set it.
 +
if ENV['HOME'].nil?
 +
  require 'etc'
 +
  ENV['HOME'] = Etc.getpwuid.dir
 +
end
 +
</source>
 +
("require 'etc' apparently refers to [https://ruby-doc.org/stdlib-2.5.3/libdoc/etc/rdoc/Etc.html the Ruby Etc module].) The debug line now outputs <code>HOME IS [/home/vbzo]</code>, so that seems like it's working and I commented out the debug line.

I don't know why it insists on having a development database when I'm not doing development (the above debugging and patching aside); I copied the production db specs to the development db section.

Redmine: download

The download/install instructions suggest strongly that using subversion is the best way to upgrade -- 

svn co https://svn.redmine.org/redmine/branches/4.0-stable redmine-4.0

...and then cd to the redmine-4.0 folder which that creates, and: 

svn update

I think this assumes I'm working with an already-configured instance, though, so I should look at the installation guide before trying the svn update.

On further reflection, I realized that I should probably be installing v4.1, in spite of the example: 

svn co http://svn.redmine.org/redmine/branches/4.1-stable/ redmine-4.1

That seemed to work too.

Ruby

It looked like the packaged version of Ruby (2.5.1p57 (2018-03-29 revision 63029)) would be ok -- Redmine 4.1 wants Ruby 2.3, 2.4, 2.5, or 2.6 and Rails 5.2 -- so I did that.

Rails

I was never able to find actual instructions for installing Rails (unless you're serving from Windows or Mac for some reason), but a hint somewhere suggested that it could be installed with gem: 

root@cloud1:~# gem install rails
Fetching: concurrent-ruby-1.1.5.gem (100%)
Successfully installed concurrent-ruby-1.1.5
Fetching: i18n-1.8.2.gem (100%)

HEADS UP! i18n 1.1 changed fallbacks to exclude default locale.
But that may break your application.

If you are upgrading your Rails application from an older version of Rails:

Please check your Rails app for 'config.i18n.fallbacks = true'.
If you're using I18n (>= 1.1.0) and Rails (< 5.2.2), this should be
'config.i18n.fallbacks = [I18n.default_locale]'.
If not, fallbacks will be broken in your app by I18n 1.1.x.

If you are starting a NEW Rails application, you can ignore this notice.

It took some puzzling to work out that the key part of that message was: 

can't find header files for ruby at /usr/lib/ruby/include/ruby.h

...suggesting that the Ruby header files (presumably in the ruby-dev package) need to be installed.

Having installed them, we will try again...

Presumably we just need to install zlib... but searching for "zlib" in apt came up with several packages:

zlib1g compression library - runtime
zlib1g-dbg compression library - development
zlib1g-dev compression library - development
zlibc An on-fly auto-uncompressing C library
zopfli zlib (gzip, deflate) compatible compressor

Our first guess was zlib1g, but that was already installed. Searching for the error came up with a post by someone who had solved it with zlib1g-dev, so we tried that next... and it appears to have succeeded:

Redmine config

Looking through my main Redmine documentation, I saw mention of Redmine/rake, and the rake about command which reports on what Rails frameworks are available. I figured that if nothing else, Rails needs to be available. 

root@cloud1:~# rake about
rake aborted!
No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb)

(See full trace by running task with --trace)

Okay, so maybe we need to be in Redmine's project folder... 

root@cloud1:~# cd /home/vbzo/domains/rm.vbz.ovh/site/svn/redmine-4.1
root@cloud1:/home/vbzo/domains/rm.vbz.ovh/site/svn/redmine-4.1# rake about
Please configure your config/database.yml first
Could not find gem 'rails (= 5.2.4.1)' in any of the gem sources listed in your Gemfile.
Run `bundle install` to install missing gems.

This feels a bit like skipping around arbitrarily, but maybe I should run bundle install at this point?

Part of the problem may be that I installed Rails 6, but Redmine is apparently configured to demand 5.2.4.1 and nothing else... 

root@cloud1:/home/vbzo/domains/rm.vbz.ovh/site/svn/redmine-4.1# bundle install
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application for all non-root users on this machine.

Bundle complete! 30 Gemfile dependencies, 81 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.
Post-install message from i18n:

HEADS UP! i18n 1.1 changed fallbacks to exclude default locale.
But that may break your application.

Please check your Rails app for 'config.i18n.fallbacks = true'.
If you're using I18n (>= 1.1.0) and Rails (< 5.2.2), this should be
'config.i18n.fallbacks = [I18n.default_locale]'.
If not, fallbacks will be broken in your app by I18n 1.1.x.

For more info see:
https://github.com/svenfuchs/i18n/releases/tag/v1.1.0

I don't get why "installing your bundle as root will break this application for all non-root users on this machine", since as far as I can tell they're always installed as root-owned. The old install on cloud4, which was done with apt, has /var/lib/gems and all its contents owned by root, so I think that's the way it's supposed to be. Maybe the Gemfile gets root-owned? That'll get taken care of later when I re-chown the Redmine project folder (before trying to run it).

Redmine folder setup

Removing the original public_html folder because it's empty and I want to use Redmine's public folder for that. I could point Apache directly at <redmine folder>/public, but when given a choice I'll do things where reconfiguration does not require restarting anything. 

root@cloud1:/home/vbzo/domains/rm.vbz.ovh/site/svn# cd redmine-4.1/
root@cloud1:/home/vbzo/domains/rm.vbz.ovh/site/svn/redmine-4.1# rmdir ../../../public_html/
root@cloud1:/home/vbzo/domains/rm.vbz.ovh/site/svn/redmine-4.1# ln -rs public ../../../public_html

2020-02-12

It remains unclear where Redmine (especially the new one) expects config files to be.

On cloud4 (old installation), configuration files are in /etc/redmine/default, which is linked from the main project folder: 

/usr/share/redmine/instances/default/config

is a link to 

/etc/redmine/default

-- but where is it set that Redmine expects to see instance-configuration folders in <redmine-folder>/instances? New Redmine doesn't have an instances folder.

Looking through the new install for anything that might be pointing at configuration files/folders, I found appveyor.yml, but that seems to be part of something called AppVeyor which is some kind of continuous-integration service (i.e. part of Redmine's development process) and not part of installing or running an instance.

Skipping around a bit -- when I try to access the instance, I get this error:

2020-02-12.screen.Forbidden error.png

This looked like an Apache error, so I checked Apache's error log and it seems to support this:

[Wed Feb 12 20:18:22.406987 2020] [autoindex:error] [pid 28388] [client 107.15.53.219:5345] AH01276: Cannot serve directory /home/vbzo/domains/rm.vbz.ovh/public_html/: No matching DirectoryIndex (index.html,index.htm,index.php) found, and server-generated directory index forbidden by Options directive

I had changed the DirectoryIndex (in Apache's config for this domain) to dispatch.fcgi, which evidence suggests is what Redmine uses for an index file, but the error suggests that Apache is still looking for index.* files.

I thought I had restarted Apache after making that change but apparently I hadn't, because restarting it resulted in a different error:

2020-02-12.screen.Internal Server Error.png

Looking for evidence of how Apache is supposed to be configured for .fcgi files... The new Redmine comes with a file called htaccess.fcgi.example which one presumes is supposed to be renamed .htaccess (or maybe htaccess.fcgi? and how would that get invoked?) but there are no instructions.

In any case, that file contains the code: 

<IfModule mod_fastcgi.c>
    AddHandler fastcgi-script .fcgi
</IfModule>
<IfModule mod_fcgid.c>
    AddHandler fcgid-script .fcgi
</IfModule>

Meanwhile, the site-config on cloud4 (old server) has this: 

       Options +ExecCGI
       AddHandler cgi-script .fcgi
       DirectoryIndex dispatch.fcgi

       # RAILS-SPECIFIC STUFF
       
       RailsBaseURI /
       PassengerUser vbz-net

I copied those lines into the site-config on cloud1 (new server), but Apache didn't like them. Investigation revealed that RailsBaseURI is the first problem -- presumably Rails directives aren't being recognized because Apache needs a Rails module enabled.

Disabling those two lines for now leaves us with this in the Apache error log:

[Thu Feb 13 01:03:23.890549 2020] [cgi:error] [pid 5631] [client 107.15.53.219:55937] AH01215: Please configure your config/database.yml first: /home/vbzo/domains/rm.vbz.ovh/public_html/dispatch.fcgi

This is at least a clue towards the "where should the config files go" question.

At that point I copied the two .example files to new names:

  • configuration.yml.example → configuration.yml
  • database.yml.example → database.yml

I still don't know where they are supposed to go, but now maybe I have a test to see if they're in the right place? I've put the renamed copies in the same folder as the original example files.

2020-02-13

part 1

I'd imported the Redmine database earlier but not created a user for it; did that now, and configured database.yml with the appropriate credentials. I now get this error in Apache's log:

[Thu Feb 13 14:37:21.489459 2020] [cgi:error] [pid 1539] [client 107.15.53.219:29345] AH01215: /var/lib/gems/2.5.0/gems/bundler-2.1.4/lib/bundler/resolver.rb:290:in `block in verify_gemfile_dependencies_are_found!': /home/vbzo/domains/rm.vbz.ovh/public_html/dispatch.fcgi [Thu Feb 13 14:37:21.489940 2020] [cgi:error] [pid 1539] [client 107.15.53.219:29345] AH01215: : Could not find gem 'mysql2 (~> 0.5.0)' in any of the gem sources listed in your Gemfile. (Bundler::GemNotFound): /home/vbzo/domains/rm.vbz.ovh/public_html/dispatch.fcgi

followed by what looks like an execution-stack trace.

I think this means I need to install the mysql2 gem, which I think I might know how to do.

part 2

I'm testing a theory about why gem sometimes complains about being run as root, so I ran it as root: 

root@cloud1:/home/vbzo/domains/rm.vbz.ovh/site/svn/redmine-4.1# gem install mysql2

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /var/lib/gems/2.5.0/extensions/x86_64-linux/2.5.0/mysql2-0.5.3/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /var/lib/gems/2.5.0/gems/mysql2-0.5.3 for inspection.
Results logged to /var/lib/gems/2.5.0/extensions/x86_64-linux/2.5.0/mysql2-0.5.3/gem_make.out

Looking at mkmf.log, the key seems to be lines ending in "-------------------- <yes/no>", where the first and only "no" line is: 

find_library: checking for -lmysqlclient... -------------------- no

So presumably I need to install lmysqlclient. (From apt, I hope?)

part 3

This article suggested that the package might be called libmysqlclient-dev, so I searched apt for "libmysql" and found default-libmysqlclient-dev, which I installed.

I then tried gem install again: 

root@cloud1:/home/vbzo/domains/rm.vbz.ovh/site/svn/redmine-4.1# gem install mysql2
Building native extensions. This could take a while...
Successfully installed mysql2-0.5.3

...and all appears right with the world.

part 4a

Now what error do we get?

[Thu Feb 13 19:19:58.871510 2020] [cgi:error] [pid 28015] [client 107.15.53.219:7649] AH01215: /var/lib/gems/2.5.0/gems/yard-0.9.24/lib/yard/config.rb:95:in `expand_path': couldn't find login name -- expanding `~' (ArgumentError): /home/vbzo/domains/rm.vbz.ovh/public_html/dispatch.fcgi

part 4b

Experimentation determined that Apache was not setting the $HOME environment variable, which was probably causing this failure. After some futzing around it finally dawned on me that this is probably what those two Rails-specific Apache directives -- 

        # RAILS-SPECIFIC STUFF
        RailsBaseURI /
        PassengerUser vbzo

-- which I had commented out -- were intended to remedy. It therefore was necessary to install whatever thing made it possible for Apache to recognize them, which turns out to be Phusion Passenger.

False start: I initially tried installing them from apt, but this led to an error about bundler being too old (despite the bundler gem being of the needed version, 2.14, where the requirement was at least version 2.

After some further dead-end futzing around, I realized that installing Passenger from apt had probably brought in a bunch of outdated stuff including bundler, so all that needed to go away and Passenger needed to be installed from a current source:

  • dirmngr is already the newest version (2.2.4-1ubuntu1.2).
  • gnupg is already the newest version (2.2.4-1ubuntu1.2).

What would you like to validate?
Use <space> to select.
If the menu doesn't display correctly, press '!'

   ⬢  Passenger itself
 ‣ ⬢  Apache

-------------------------------------------------------------------------

Checking whether there are multiple Apache installations...
Only a single installation detected. This is good.

-------------------------------------------------------------------------

 * Checking whether this Passenger install is in PATH... ✓
 * Checking whether there are no other Passenger installations... ✓
 * Checking whether Apache is installed... ✓
 * Checking whether the Passenger module is correctly configured in Apache... ✓

Everything looks good. :-)

I restarted Apache, but it didn't seem to make any difference; still getting the same error, although the form has changed slightly: 

[Thu Feb 13 21:53:57.611810 2020] [cgi:error] [pid 3113] [client 107.15.53.219:31393] AH01215: /var/lib/gems/2.5.0/gems/yard-0.9.24/lib/yard/config.rb:95:in `expand_path': /home/vbzo/domains/rm.vbz.ovh/public_html/dispatch.fcgi

I confirmed that the error means what I think it means by putting this line right before config.rb line 95: 

system("echo HOME IS [$HOME]")

This returns malformed header from script 'dispatch.fcgi': Bad header: HOME IS [] as expected.

Googling the current version of the error message, I found that someone had fixed the problem like this (forgot to save the link, but there's a more compact version here) - inserted before the debug line: 

# The HOME environment variable is important when invoking Bolt. If HOME is not
# already set, set it.
if ENV['HOME'].nil?
  require 'etc'
  ENV['HOME'] = Etc.getpwuid.dir
end

("require 'etc' apparently refers to the Ruby Etc module.) The debug line now outputs HOME IS [/home/vbzo], so that seems like it's working and I commented out the debug line.

Next error: 

[Thu Feb 13 22:09:03.093211 2020] [cgi:error] [pid 8348] [client 107.15.53.219:61505] AH01215: /var/lib/gems/2.5.0/gems/activerecord-5.2.4.1/lib/active_record/connection_adapters/connection_specification.rb:260:in `resolve_symbol_connection': 'development' database is not configured. Available: ["production"] (ActiveRecord::AdapterNotSpecified): /home/vbzo/domains/rm.vbz.ovh/public_html/dispatch.fcgi

I don't know why it insists on having a development database when I'm not doing development (the above debugging and patching aside); I copied the production db specs to the development db section.

Next error: 

[Thu Feb 13 22:12:21.144585 2020] [cgi:error] [pid 3108] [client 107.15.53.219:3585] AH01215: /var/lib/gems/2.5.0/gems/activesupport-5.2.4.1/lib/active_support/dependencies.rb:291:in `require': cannot load such file -- fcgi (LoadError): /home/vbzo/domains/rm.vbz.ovh/public_html/dispatch.fcgi

part 5

Following instructions here, I created a Gemfile.local with the contents given, and now the error is: 

[Thu Feb 13 22:39:30.995554 2020] [cgi:error] [pid 12890] [client 107.15.53.219:48801] AH01215: /var/lib/gems/2.5.0/gems/bundler-2.1.4/lib/bundler/resolver.rb:290:in `block in verify_gemfile_dependencies_are_found!': Could not find gem 'fcgi' in any of the gem sources listed in your Gemfile.

Could it be this simple? 

root@cloud1:/home/vbzo/domains/rm.vbz.ovh/site/svn/redmine-4.1# gem install fcgi
Fetching: fcgi-0.9.2.1.gem (100%)

At first I thought the error message was unchanged, but then I realized the timestamp I was looking at was the same as before. Apparently these are now the most recent messages: 

[Thu Feb 13 22:39:31.000685 2020] [cgi:error] [pid 12890] [client 107.15.53.219:48801] End of script output before headers: dispatch.fcgi

...and, like, what is actually the problem there? This is not helpful.
