I was following these instructions: How to upgrade to Qubes 4.1 | Qubes OS
Downloading qubes-dist-upgrade worked fine, but when I tried to do the upgrade with:
sudo qubes-dist-upgrade --all
I get the error message:
ERROR: UpdateVM (sys-whonix) should be at least Fedora 30 or Debian 11 template based VM.
Is it not possible to do the in place upgrade over sys-whonix?
