In a world where nothing seems to work anymore, especially anything related to tech and/or customer service, getting on my laptop running Linux Mint just feels like a breath of fresh air. And that goes for just about any distro. It’s nice to have something that works as it should and doesn’t seem to go out of its way to cause frustration and irritation.
(P.S. Loblaw’s/PC Express suck ass. Canadians will know what I’m talking about).
I had a somewhat similar issue on my work laptop a short while ago, when I installed a program, which included a bugged XML settings file, then ran system update. When the updater tried to rebuild some caches (related to ie. icons, MIME etc.), some programs which use these caches simply stopped working. Reinstalling all packages with apt was the only thing that helped, to this day I do not even know all of the parts of my system that were broken.
But this was one of these issues that happen once per 5 years, and leave you scratching your head and asking “what the hell is going on here?”. The difference from Windows is that in Linux, you can have a high understanding of system’s internal modular components (at the cost of time needed to learn it), and regular system issues can be identified after a few minutes of Googling.
The KeepassXC-browser stuff is most likely from when Ubuntu started pushing snaps. For a while this was broken, and even if you installed Firefox from a PPA instead it still wouldn’t work due to a default AppArmor policy blocking the connection.
