[DRE-maint] Redmine in buster

[Marc Dequènes (duck)]

Quack,

I saw your work was already included in the repo, that's fine. I would 
suggest merging your patch with 
0001-Gemfile-relax-some-dependencies.patch because it doing the same 
things on a smaller scale and would simplify maintenance. This is not 
urgent though. I would change the Author field to use the team, as it 
would merge work from Antonio and myself, maybe Kanashiro-san too, so 
that would be more appropriate I believe.

I've prepared the upgrade to 4.0.4, it builds fine but I've got problems 
with running the tests. Seems the switch to LXC 3 was not as seemless as 
expected. I recreated a new LXC testbed after fixing the network config 
in the setup script but after the testbed apt upgrade it fails with:
autopkgtest [15:02:55]: testbed dpkg architecture: amd64
Unexpected error:
Traceback (most recent call last):

I did not find anything that match my case on the Internet yet, so help 
appreciated.

Anyway, I
ll have a break and go on with this later so we can have your work and 
an up-to-date version to test and polish.

Regards.
