Upgrade R4.1 --> R4.2, Cannot Complete Stage 1 (updating template and standalone VMs)

I’m having some issues upgrading from 4.1 to 4.2. Every time I attempt to use

sudo qubes-dist-upgrade --all-pre-reboot -y

, I get some issues. Output looks like this:

---> (STAGE 1) Updating Templates VMs and StandaloneVMs...
whonix-gw-16: OK
whonix-ws-16: OK
<user-created-VM-1>: ERROR (exit code 20, details in /var/log/qubes/mgmt-<user-created-VM-1>.log
<user-created-VM-2>: ERROR (exit code 20, details in /var/log/qubes/mgmt-<user-created-VM-2>.log

This happens for multiple VMs I’ve created, and trying again sometimes gets some of them to be OK but not always. I can delete some of these and proceed while restoring backup data later, but there are a few that I really don’t want to delete. I really just want to upgrade in place.

The log messages boil down to failing to get release files for debian/whonix-based VMs (connection refused) or failed to download metadata for repo 'fedora'. Annoying stuff.

Has anyone seen this yet?

The issues that I’m seeing appear to be connection issues. The logs for my whonix-ws-16 VMs that are failing consistently have the following:

E: failed to fetch tor+https://deb.debian.org/debian/dists/bullseye/InRelease  Could not connect to ( - connect (111: Connection refused)
E: failed to fetch https://deb.qubes-os.org/r4.1/vm/dists/bullseye/InRelease Something wicked happened resolving 'deb.qubes-os.org:https' (-4 - Non-recoverable failure in name resolution)
