Mythbuntu has been stable on my kit for years
Sad to see it go, I have upgraded without problems since the first Mythbuntu release.
I run Mythbuntu as a backend server with Kodi on a Pi and various Android clients.
My mythbuntu server also runs PHPmyadmin, Nextcloud, Motioneye, and a couple of other database apps, plus doubling as a general use pc and a digital photoframe.
MythTV is awesome, and I will probably move to Ubuntu with XFCE and Mythtv.
Mythbuntu just made it all a lot easier.
