From my understanding, it looks like since the file "/usr/share/pixmaps/sos-playlist-editor-icon.png" is part of two packages, and only one is being updated (where the icon is also being updated), Ubuntu is not happy about that situation.
I've tried through the automatic software updater tool, as well as a sudo apt-get upgrade as well, with no luck.
We are able to get this package installed if we issue a command to the terminal, namely:
sudo apt upgrade -o DPkg::options::="--force-overwrite" sos sos-playlist-editor
and this works fine and will install and upgrade the package. However, we don't want our users to have to run this command. Is there a better solution to this issue? Ideally, I'd like to have this package installed with normal updates.
