i looked up multiple guides to enable flatpaks and all i achieved was that i could install them from terminal, but the apps never actually appeared so i couldn’t run them.
took me a while to realize the default store is snap only, but i couldn’t install another store either (can’t remember why). if i wasn’t so pissed i probably could’ve figured it out, but steam not working was too much of a dealbreaker that it wasn’t worth the effort

i don’t recommend ubuntu anymore. recently tried it on my laptop and holy hell it’s bad. couldn’t install flatpaks and the only way to install from repo was to use terminal. couldn’t get any version of steam to work at all. and I’ve been a linux user for years now…

also for some reason mint wouldn’t install on the same thinkpad, the installer wouldn’t boot at all, just gave some grub message. also fedora was no success, the usb media wasn’t recognized. ultramarine finally worked even though it’s just fedora with tweaks. some say it’s a bad thing to have tons of distros, but for me it’s been a blessing. one distro won’t work for every pc.
