I’m following the guide at https://www.qubes-os.org/doc/upgrade/4.2/#clean-installation to upgrade from R4.1 to R4.2 via the clean installation approach. Unfortunately, step 3 errors:
$ sudo qubes-dist-upgrade --template-standalone-upgrade

This is an issue in v4.1.6 of the tool. Downgrading with sudo qubes-dom0-update qubes-dist-upgrade-4.1.5 solved the issue for me. Either the upgrade guide or qubes-dist-upgrade should change.
