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.

Building native extensions. This could take a while...

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...
