Some images don’t have an installer, like the COSMIC variant, or the ISO is outdated.
NOTE
When switching from a known good image to another one, use this command to permanently save the known good image, before running other commands: sudo ostree admin pin 0
Nice guide, though number 3 is numbered as 2 there.
As a note, if you do rebase to ublue, there may be issues rebasing back to Fedora. I think the main issue was Bazzite, as I’ve once rebased from Aurora, to Bazzite, then back to Aurora which resulted in a black screen when I rebooted.
I’m sure it’s just something in the config that I could revert, but be careful nonetheless. Just because the OS is Atomic, doesn’t mean everything in the OS is Atomic.
The main reason isn’t just technical. Generally speaking it works, the main reason is support and expectations. No one is sitting there testing this over every iteration of everything. So this is a scope issue, one of those “no is temporary, yes is forever”.
If a bunch of people show up to test it all and deal with support and fixes then it’d be a different story. But like, who would want to sign up for this? I would hate doing this I’d be so miserable. For free too? This is also why we don’t do it, most of us installed the OS and left it there – cloud native is about making the decision earlier, shifting left, blah blah.
