I can not update dom0.
The problem comes long ago, I found a “solution” by setting the update VM on dom0 to sys whonix. With update VM sys firewall I got “/usr/liv/qubes-download-dom0-updates.sh: No such file or directory”.
With update VM sys whonix it worked well for a long time. But now it can not reach any update server (also changed some tor ips, but without any effect).
I did nothing on dom0 and nothing of sys firewall or sys whonix. Just updated them in a regular way.
Anyone any idea?
