Progress on documenting Qubes specific 10 -> 11 upgrade issues has been made:
There are a few Qubes specific issues to solve. Documentation on how users can work around those.
Updating Qubes App Menus... (/usr/lib/qubes/qubes-trigger-sync-appmenus.sh) runs forever. Locked up 5 times now. (Manually edited that script to disable this for now so the upgrade runs through.)
When that happens, we could advice users to open another terminal and to run:
sudo killall qubes-trigger-sync-appmenus.sh
But that solution is not great because it makes the upgrade process cumbersome, tedious. Any better idea?
TODO: provide debug output to Marek as per https://groups.google.com/d/msg/qubes-users/MoUqGfMpMu0/GQfKwN1jBgAJ
Currently upgrading Whonix-Workstation template. Will test upgrade a Whonix-Gateway template soon. Upgrade is slow. Still running. There may or may not be other issues during upgrading or after restart.
