Oh cool!

LxQT maybe? Ubuntu MATE could work too.

With btrfs I would just do a snapshot before an upgrade then restore if it broke.

Yeah same here. I would be happy using Firefox as a flatpak or snap if everything worked ootb.

I know. I just installed the latest Kubuntu LTS on my system and I’m regretting it because of the Snap exclusivity. If it wasn’t for that, if I still had the option to install a .deb from Ubuntu’s repos, it would be great. But, that’s sadly not the case.
