today I tried to upgrade from 16.04 to 18.04 using
sudo apt-get -f upgrade
Now, Gnome isn't starting anymore. I tried "safe mode", but it feels like everything is giving me failure notices.
An upgrade from "xenial" to "bionic" is not supported with this tool
failsafeX delivers a black screen. "network" delivers:
grep: /etc/resolv.comf: No such file or directory
Does anyone know, what to do?
If there is no backup you could use a live session to extract your personal data from the disks and put them on an external disk. Do detach it safely before installing so there is no connection to it.
