Cannot create new standalone Qube with UI

[incalzando-a]

Qubes OS release

4.2.1 (R4.2)

When using "Create New Qube" application, to create a standalone Qube, I encounter the error "An error occurred: Got empty response from qubesd. See journalctl in dom0 for details".

journalctl output:

Jun 13 10:42:57 dom0 qubesd[40029]: unhandled exception while calling src=b'dom0' meth=b'admin.vm.Create.StandaloneVM' dest=b'dom0' arg=b'' len(untrusted_payload)=31

I've tried with all template and settings, but still receive this error. I think it might be a signing error somewhere.

Did you by any chance put a space in the name of the new Qube? I got the same output in journalctl, see:
#9558

The PR for #9558 should fix this as well. This issue could be closed.
