What happened: I was updating dom0 (qubes-dom0-update) and it seemed to freeze after installing everything. It was erasing old kernels, step 12/12. Eventually I ctl-c a few times to get out of there. I ran qubes-dom0-update again and it ran with no errors, showing the items I’d just installed but didn’t seem to do anything. At this point I decided to reboot and now I get a kernel panic and cannot boot into Qubes.
What I have: A backup of my system including dom0, with old versions of other qubes. My current system that won’t boot.
My plan: My thought was to take the back up dom0 and restore it to my current system to try to fix this. Let me know if you think there’s a better way.
-
recover my old dom0 using this: https://www.qubes-os.org/doc/backup-emergency-restore-v4/
-
copy it over to my current system
I have not done either step, but I’m assuming the instructions in step 1 will work.
I’m trying to figure out how/if i can do step 2. If I open up my encrypted backup I get
qubes_dom0-pool00
qubes_dom0-pool00_tdata
qubes_dom0-pool00_tmeta
qubes_dom0-pool00-tpool
qubes_dom0-root
qubes_dom0-swap
and all my vm’s. I’m guessing qubes_dom0-root is where I would restore my dom0 backup to? If so, can I just rsync everything from the restored backup dom0 to there?
I’m also concerned that my grub config might be a problem, but not sure how to check on that.
Thanks for reading and any tips you can offer. Hoping to get this figured out today
