[PROBLEM] Distribution upgrade to Buster fails

[jakenl]

I have tried many things and at the end I decided to go back to Stretch, for the time being.

I checked the sources.list and xbian.list. Both were pointing towards Buster
I checked the xbmc.log file and it states 'segmentation fault'
SSH doesn't work anymore, so I need to use an USB keyboard and work on the HDMI-screen (this works)
Service xbmc restarts fails
I checked the cmdline.txt, but that looked original
I checked config.txt and no different than normal
Same thing for /etc/fstab
I tried to reboot without additional USB-sticks, USB-keyboard and network cable: no difference

I changed the xbian.list to 'staging'. This generated a whole new list of upgradeable packages, including an alpha version of Kodi 19. I expected this to run, but the same result as mentioned in the previous posts, no change to be seen there.

The only thing I can guess now, is that it have to do with me booting from an USB-stick on my RPI3 instead of from a SD-card. Maybe the script can't handle that.

With the time spent, I might be better of with a fresh Buster image and reinsert my 'xbian-backup-home'. Would that work? I will also need to reinstall some other stuff that I run on the side on this RPI, but if I have documented everything properly for myself, it might save time at the end.
