I have installed Qubes 4.1 rc-1 on my PC. I was already testing 4.1 previously with minimal templates for last 1 year but freshly installed release candidate 1. I tried to install debian 11 minimal template on RC.
qvm-template install --enablerepo=qubes-templates-itl-testing debian-11-minimal
It fails with
Error: Download failed
Issue remains same even after 1 repeat install and with
sudo qubes-dom0-update equivalent command.
