I don't use Mint, but I would guess that you could change your repos in /etc/apt/sources.list
, run sudo apt update
, and then sudo apt full-upgrade
. Just make sure the full upgrade isn't doing really dumb stuff like deleting a bunch of programs.
I could be completely wrong and this could be terrible advice, but this has become the wisdom for me when I use Debian Testing. Of course, I just did straight sudo apt update
after Bookworm was released and the upgrade to Trixie went mostly fine. I have never upgraded between stable versions, so I may not be one to say.
I agree with Mint. I think Ubuntu has kind of devolved though, and PopOS is the better way to go. Fedora's good too these days.
My recommendation is to try out a few distros in VirtualBox before switching - this was my process, and it can be very gradual.
