I’m going to choose a VM.

Tried it several times! Didn’t fix the issue…

I don’t think mintinstall lets you change where you’re installing the program… Interestingly, I ran flatpak search libreoffice again and it quickly returned some packages, which it didn’t do before. Still can’t install anything though…

Linux Mint is supposed to come with Flatpak support by default. Running flatpak remotes shows that I have flathub configured:

Name    Options
flathub system

That said, thank you for answering! I appreciate it, even if it doesn’t solve my issue.

Write. Anything you like. Nonsense, the issues of the world, a memory, a story. Sometimes, things (thoughts/memories) hurt less when written. Then you can burn the paper. Or tear it. Or do nothing with it. But burning it feels so good. It’s like burning your sad thoughts.
