Your experience is very different from mine. I usually have to dig in and fix crap that shouldnt be wrong in ubuntu long before I even get to the upgrade phase! Lots of circular problems: oh this snap doesn’t have the full dependencies. Thats ok, I know how to edit them. Except that didn’t work, so lets add the PPA. But that was out of date, lets build from scratch… and so on.
Edit: Let me add something: Glad it worked for you. And Ubuntu is Linux, and we have that in common, and I want to make sure this type of discussion is always framed under “SAME TEAM!”
Onlyoffice seems a little slack on the security and updates. I saw the warnings in the desktop package, have they made sure the online offerings are secure?
