It once was a Debian that just worked, nowadays is some kind of a trap. As you start getting deeper you start to notice non-standard things that get in the way more than they should, besides being utterly non-standard.
Things i noticed so far:
- auto-update enabled by default. if I boot a vm it's going to be nearly unusable (can't install packages) because it's going to spend the first 30 minutes doing a full upgrade
- netplan -- not sure why that's there
- snaps. for everything. the last straw for me was realizing that gnome-calculator packaged as a snap. it took almost 20 seconds to show the f-ing calculator. every time an app is slow i suspect that's because it's packaged as a snap.
- doing weird stuff with motd. why?
At this point my next reinstall will be a good old Debian.
