I have an ubuntu system (dual booted with windows) that shut down during an upgrade from 20.4 to 21.10. It does not manage to boot.
I can enter recovery mode and drop into root shell. I have an external hard drive with a restic system backup from right before starting the upgrade (done as described in the docs). I want to restore my system.
I have no experience with restoring back ups. I tried simply mounting the hard drive to /mnt/restore and then running
restic restore latest / on the repo. In the middle of a restore, it start outputting errors about “transport endpoint not connected” like so:
I currently cannot connect to the internet.
How should I run this backup? Is there something I did wrong, or is this a different problem.
(I also have an additional separate backup with all of my personal data and most of my configurations. In the worst case, I will reinstall ubuntu or another dist and start from there)
