[PROBLEM] Distribution upgrade to Buster fails

[Nachteule]

And, you can do a manual upgrade to see directly what happens:

1) change all stretch to buster in file /etc/apt/sources.list and /etc/apt/sources.list.d/xbian.list
2) run sudo apt-get update
3) DEBIAN_FRONTEND=noninteractive sudo apt-get dist-upgrade -y --allow-downgrades -o Dpkg::Options::=--force-confdef -o Dpkg::Options::=--force-confold 2>&1 | tee /tmp/aptstatus
4) sudo apt-get install --reinstall xbian-update

in 3), you have to look which packages will be REMOVED and it is important that upstart and xbian-package-xbmc is not removed and elogind will be installed

Please note: you should not run this in a ssh session, because usually connection will be lost during apt-get run and this wil interrupt the upgrade process
