... and the solution from #5138 (comment) works as well.

Install instructions for Ubuntu 24.04 LTS (‘libappindicator0.1-cil’ has no installation candidate) has more information.

I cited topic here while making the request that the upcoming Beta can have a fix for 24.04, despite the poor timing.

@ts678 I missed the comment. Looking at #5138 I cannot see what the updated package is named?

Based on the error message, gtk-sharp2 seems to be missing from the repos, so it would be hard to fix.

Is there a known alternate library?

Is there a known alternate library?

Install instructions for Ubuntu 24.04 LTS (‘libappindicator0.1-cil’ has no installation candidate)

seems to have updated libappindicator and it dodged the missing gtk-sharp2. Going to GTK 3 makes sense because:

Install instructions for Ubuntu 24.04 LTS (‘libappindicator0.1-cil’ has no installation candidate)

Drop support for GTK+2.0 (libappindicator1, libappindicator-dev,
libappindicator0.1-cil, libappindicator0.1-cil-dev).

So maybe right blend is

Package: libappindicator3-1 (12.10.1+20.10.20200706.1-0ubuntu5) [universe]

Package: gtk-sharp3 (2.99.3-4.1build2) [universe].

but there might be a question of how to make a .deb that works everywhere, and fails at install time if it has no chance.

It probably needs sorting out by somebody who's better with Debian dependencies, but users have done some testing.
