For ages now, I've been using two servers, one live and another to install the new version on and test. I know there has to be a better way. I use OpenSUSE because it's the one I know best, going from one version of Leap (the name of OpenSUSE's stable releases) to the next as they come out. They also have a rolling version called Tumbleweed.

Beware! I got bitten thus

I built drivers, needing the kernel stuff, time passed but I had to go back to update a driver that worked with kernel n-2 but not n (v4l API is all over the place)
Eventually I licked wounds, defeated!
Tumbleweed goes not provide previous releases.

Could that relate to mythtv. Like so ..
On tumbleweed n- mythweb worked
On version n it stopped working (python)
Go back to version n-. Yay I’ve got the iso. Unfortuantely zypper won’t play.
No mythweb !!

If you need/want a rolling distro arch looks better (but I’ve not played enough yet)
manjaro or endeverOS may give you a gentler install experience.

The mythtv devs seem to like ubuntu, which I dislike, if you use SuSE then say no more.
But ubuntu experience is works-well, specially if you build packages.

Then maybe with some cleverness with grub I can swap to the new version, booting straight into it without KVM, not needing KVM again until the next update.
