Upgraded to 4.3 from 4.2 caused dom0 to break!

Qoobsnoob · March 30, 2026, 5:04pm

For context, I have upgraded from qubes 4.2 to qubes 4.3 by completely reinstalling qubes for 4.3 from a USB stick. I restored everything from Q’s 4.2 from my backup. Everything was working fine until I restarted my computer. The USB mice and keyboard still work, however nothing else works. In the screenshots below, I have tried to open restore qubes application and qubes template manager. The qubes manager does not open at all.

Please help me. I don’t want to spend another four hours reinstalling and restoring everything.

Please post the outputs of:

sudo systemctl status qubesd

sudo journalctl -xeu qubesd.service

(Run them in the dom0 Xfce terminal)

While I feel like it’s possible to get to the bottom of this through debugging here in the Forums, I think it may just be faster for you to restore again (maybe piece-by-piece, to see if something specific causes breakage).

Qubesd.service: main process exited, code=exited, status=1/FAILURE. Failed with exit-code

Failed to start qubesd.service
Scheduled restart job, restart counter is at 15

File /usr/bin/qubesd, line 5, in
Sys.exit(main))
And several other errors like this for different files
