Update: I could resolve the problem after a fresh reinstall in UEFI mode with new formatted USB device.
After fresh installation of Qubes OS 4.1 no matter if UEFI or Legacy no VMs were created.
In the initial configuration menu under Templates Configuration the following lines are not checked and grey:
“Fedora not available”
“Debian not available”
“Whonix not available”
After confirming to finish the initial configuration I receive following message:
Qubes initial configuration failed. Login to the system and check /var/log/salt/minion for details. You can retry configuration by calling ‘sudo qubesctl --all state.highstage’ in dom0 (you will get detailed state there).
/var/log/salt/minion shows among other events:
[salt.pillar] [CRITICAL] Specfied ext_pillar interface qvm_prefs is unavailable
[sat.state] [ERROR] =====['present']=====
qvm.create: error: the following arguments are requited: vmname

app: Error creating VM: Got empty response from qubesd. See journalctl in dom0 for details.

Calling sudo qubesctl --all state.highstage result in similar errors ending with
At the end of the install process before reboot I checked via tmux session panes (CTRL-ALT-F2) that in /mnt/sysimage/var/lib/qubes/template-packages there were no files.
I executed
dnf config-manager --add-repo /tmp/installer.repo Unable to detect release version (user ‘–releaseserver’ to specify release version) adding repo from: file://tmp/installer.repo
and
dnf download --downloaddir=/mnt/sysimage/var/lib/qubes/template-packages qubes-template-* Unable to detect release version (user ‘–releaseserver’ to specify release version) 3.8 MB/s | 3.0kB 00:00 anaconda
Then I did a reboot but nothing changed in the initial configuration menu.
