over the course of a few updates, they replaced half of your programs with snaps (without telling you),
You don’t need to lie. A full list of debs that have been transitioned to snaps is:
- Firefox
- Thunderbird
- Chromium
Sorry, I might have misremembered the exact process (this was probably three or four years ago), though no need for the nasty aggressive attitude (though my apologies if I offended you somehow).
Maybe it was version upgrades (e.g 18.04 to 20.04) instead of updates, or clean installs/new installs/reinstalls? I expect it was some of one and some of another.
At the time I used to (casually) maintain a bunch of Ubuntu computers for a few community projects, small organisations and older people who live nearby. I don’t remember the specifics, I just remember the phone calls of “the printer isn’t working” “Linux has broken my USB pen” etc, and the fix being “remove the snap version and install the deb version”. It caused a lot of problems.
