Edit: actually, I think I installed it via Snap Store. And the current Snap Store version is .28, but the new update is .29. So the .28 client is just in a loop of "there is a new update and I am out of date, so now I am just a modal that downloads the packages at these URLs". Not sure where my other installation came from, if I somehow did a fresh install or what.
I don't really get why there isn't just one obvious reliable and centralized way to install software on this thing. My Slack, VSCode, and other apps auto-update without my having to manually do anything, which, IMO, is how it should be by default.
I'm on Ubuntu--is there benefit to using Pacman on there? My understanding is that people do.
