Sure it does.

This is part of your problem. Partially-upgraded systems are not really
supported by Debian. Even though we *try* to specify versioned
dependencies that force the required upgrades, the number of different
configurations in a partially-upgraded system is infinite and it's
impossible to catch all cases.

You cannot remove ruby and still expect schleuder to work at all. :)

Those should not be a problem.

This is the other half of your problem. Debian packages do not ship
*.gem files; this means these were all installed manually and could
cause dependency problems. Having gems installed is not a problem in
itself, but if you install arbitrary versions, those can cause conflicts
with the Debian packages, which were tested together in the specific
versions shipped in a Debian release. When you combine these with a
half-upgraded system, there are a huge number of things that can go
wrong.

I suggest you:

- remove all gems. you want to basically:
  - remove /var/lib/gems/3.3.0/* (but not /var/lib/gems/3.3.0 itself)
  - remove everything under the following directories that are not
    installed by a Debian package:
    - /usr/share/rubygems-integration
    - /usr/lib/x86_64-linux-gnu/rubygems-integration
    - /usr/lib/ruby/gems/3.3.0
- fully upgrade your system to Debian stable

With that done, schleuder should just work.
