It's unfortunate, and I mean this genuinely here, in a sympathetic way, that you felt afoul of the common error that people who checked in with Linux 6 or more years ago make: assuming that Ubuntu is still the best and easiest to use distribution. Unfortunately, it really isn't anymore — the way they are pushing snaps (including forcing you to install snaps instead of regular packages even if you use the regular package manager) is really unfortunate because of how fucked snaps are to use, not to mention the fact that snaps are hardcoded to only be able to install from the proprietary closed source snap repository Canonical runs, and that store is full of crypto scams. Plus, in general, desktop PC Ubuntu has been getting buggier and more unreliable over time as Canonical switches their focus to the server. Honestly, if there was one misconception about Linux that I could erase with a snap of my fingers from all potential users minds, it would be that they should start with Ubuntu. IMO Debian is a pretty good choice if you have hardware that's about 2 to 4 years old or more and don't really care about getting the latest driver updates or advances in the Linux ecosystem, so you should have a better experience there, but if it starts to frustrate you that it takes years for huge fixes and advancements to make their way to you, I really enjoy Fedora. :-) Also, you mentioned two of the major alternative application packaging formats, snap and appimage, but have you heard of our Lord and savior Flatpak? :p It has all of the benefits of snaps (namely sandboxing, consistent environments and packaging dependencies along with applications, updates directly from upstream, distribution agnostic packaging, and automatic integration with your desktop environment) but none of the downsides (namely far better desktop environment integration thanks to portals and much much faster startup times and no perf impact during runtime unlike snaps). A lot of people talk down about them but I think that's mostly FUD.
