What problem did you encounter?

Been trying to install Sober on my PC, I use Linux Mint 22 Cinnamon running on version 6.2.9. Copying and pasting the flatpak link into my terminal only leads me to an error "No such ref 'app/org.vinegarhq.Sober/x86_64/master' in remote sober". Trying to run the flatpakref itself with my software manager will close the window completely. Ive seen a few closed cases with the same issue as me spanning back a month already without any solutions. Saw that it could be a issue with the file's host but it could be a problem on my end as well, IDK. Is there any way to help me out or maybe any indication as to if or when this could be solved if its not a problem on my end?

try to install again, over the flatpak CLI, then attempt to provide as much logged information as you can that isn't identifying
flatpak install --user https://sober.vinegarhq.org/sober.flatpakref

SELinux or Apparmor messing with things, maybe?

No longer relevant, as we're on Flathub now.
