I’m not sure if this is a bug or user error, but seemingly every time I install some software, for example the flatpak version of Steam, the Pop! Shop shows an Update available, which then installs the deb version of the same application.
So I end up with two copies of Steam, two copies of VS Code, and a few more apps. Removing this extra deb version works but messes up the app icons.
What is going on?
Check your repo lists, you may have extra repos that may have been added by your app installs.
