Snaps are one of the two main reasons I'm ditching Ubuntu for basic Debian. The other is apt spam berating me to upgrade to their pay security service.
I now routinely install fake-ubuntu-advantage-tools.deb to remove Ubuntu "Advantage". It's an empty package that satisfies the dependencies.
I also remove some of the crap that Ubuntu put in /etc/update-motd.d. From memory 10-help-text, 50-motd-news, 88-esm-announce, 91-contract-ua-esm-status are pointless and annoying.
Same here, and the fact that it's way too easy to get in "you can't upgrade" -limbo with Ubuntu on servers I haven't touched for a while.
Went back to Debian stable and zero issues. The main reason I went to Ubuntu was that stable Debian used to be veritably ancient. But nowadays I run most of my software in Docker anyway, so it doesn't matter.
