Ubuntu Upgrade from 16.04 to 18.04 failed

by Fred   Last Updated May 16, 2019 06:02 AM

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.

dpkg delivers:

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?

  • Restore a backup you made so you get back to 16.04.
  • Use the 18.04 live session to install 18.04 without formatting. This should not touch your personal data. If anything does go wrong you could also ...
  • Reinstall with formatting using a 18.04 installer. Then restore the backup you made of the personal data.

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.
