Both of them sound like a Yandere simulator

I already use flatseal, I needed it to make bottles see some folders not only downloads

I have installed flatpack apps for per-user, and there are runtimes and apps in my home folder

And I just tried to run the flatpack update using sudo and it worked, I didn't know that flatpack can be used with root rights

Yep, first time I used thunar to grant rights, and after that I used crown and chmod

and after I created the jellyfin folder in /home/jellyfin, it was easier to make it work
