"apt install muon" output The following packages have unmet dependencies: muon : Depends: apt-xapian-index but it is not going to be installed E: Unable to correct problems, you have held broken packages.
Muon is obsolete, replaced with Discover. Maybe Neon should remove the package?
I installed muon a while ago and it worked just fine. -1 to removing Muon.
so what's going to happen? dependencies problem solved (good) or muon removed from repositories (bad)
Created attachment 110868 [details] docker simulation yeah, there's no problem with the dependencies. apt install -o Debug::pkgProblemResolver=true -s muon
It installs and runs fine for me on KDE neon Developer Unstable edition. Worth investigating why apt-xapian-index doesn't want to install for you
(In reply to Jonathan Riddell from comment #5) > Worth investigating why apt-xapian-index doesn't want to install for you Agree. But I don't know how to do it.
What is the output of apt install apt-xapian-index Is there any meaningful error message in that case? I believe this is not a KDE neon bug, so maybe you should seek further help on forums and such?

Today I reinstalled neon because other issues. Muon is now installed.
