Not installable on disco due to ruby-mail

[Andreas Hasenack]

redmine 3.4.x requires ruby-mail 2.6.4. From its Gemfile:
gem "mail", "~> 2.6.4"

If attempted to install on disco, we get:
Could not find gem 'mail (~> 2.6.4)' in any of the gem sources listed in your Gemfile.
dpkg: error processing package redmine (--configure):
 installed redmine package post-installation script subprocess returned error exit status 1

Disco has ruby-mail 2.7.1, and that is only supported in redmine 4.0.x:
https://github.com/redmine/redmine/blob/master/Gemfile:
gem "mail", "~> 2.7.1"

Both debian and ubuntu are at 3.4.6. So either we go ahead of debian to 4.0.x, or the package should be dropped.

I looked into updating redmine to 4.0.1 and it will be a quite significant effort.

I recommend dropping it from Disco until a new working version can be synced from Debian because the current version is already broken and holds back migration of good packages from -proposed.

I opened LP: #181327 for the removal.

disco now has redmine 4.0.1-2, and I just checked that it's now uninstallable. (Not my doing - I just happened to notice it in passing.)
