Backups fail after upgrade to RC3.1

[Gaijin]

I tried the experimental upgrade from Qubes 3.0 to 3.1 rc2.[1] The
upgrade seems to have been successful but there are a few issues.

Biggest problem is that I cannot backup. When I try to do a full backup
it gets up to about 64% and then I get a dialog, "ERROR: Failed to
perform backup: error in addproc" I have tried backing up several times
with the same error.

Next, if I shutdown the sys-net VM I cannot restart it. I need to do a
full system reboot. Often it takes 2 or 3 reboots to get the system
running again. I can boot all the way to the GUI, but then the screen
freezes and I cannot do anything. I have to manually power off and try
again.

The issue happened to me too, the problem may be related (in my case
it was) to invalid symlinks in some VM directory under /var/lib/qubes.

In my case the wrong symlinks were for some .desktop files and for the
icon.png in the root folder of the VM
(/var/lib/qubes/appvms/[vmname]/icon.png). Fixing the links solved the
backup interruption.

I did the same upgrade, but am not having these issues. There was a
problem with vms not starting during system boot, but that has hopefully
gone away.

I looked up the broken symlinks in dom0:
find ./ -type l -exec file {} \; |grep broken
There were a bunch in there from old VMs that I had deleted, but none
for the /var/lib/qubes/appvms/[vmname]/icon.png that you mentioned.
Fixing those seems to have fixed the backup problems. I can now do a
full backup. Thanks.

I still can't start the sys-net VM if I shut it down. I get, "Error
starting VM sys-net: cannot execute qr-exec daemon!

Take a look here:

In the last comment there is some workaround for it.
