ZeriBlackheart The attempt to install Store content might be breaking things, although it's interesting that repairing worked, if that's the only troubleshooting step you tried at the time. Normally, you'd fix a broken install of user files (Store content or otherwise) by removing or renaming the Sims 3 user folder, the one that's in Documents > Electronic Arts > The Sims 3 in Windows and macOS. That's where the Store content would be installed and therefore where any broken file(s) would be.
The caveat is if you've installed the game to the same location as the user files, with everything jumbled up, all bets are off, and I could see how a repair would have flushed the bad data.
Having said all that, you're the second person who's posted recently about not being able to install Store content into a Linux distro. I don't have any hands-on experience with Linux, and while I do know that some players have been able to use Store content, I couldn't tell you how. So I'd suggest you post on Mod the Sims, where last I heard, there were a few active users running some flavor of Linux. If that doesn't work out, you could ask at NRaas, which is more active but with fewer Linux users. Someone there might know where the good resources are, if nothing else.
