Hi!

I know that the issue is marked fixed already, but I wonder if there should
have been some more popular notice for this surprising change in the update
mechanism.

Today I saw there (before installing updates):
[master@dom0 ~]$ sudo qubes-dom0-update
Using sys-firewall as UpdateVM to download updates for Dom0; this may take
some time...

Qubes OS Repository for Dom0

33 MB/s |  34 kB     00:00

So (as it seems) I'll have to follow
https://github.com/QubesOS/qubes-issues/issues/6581
Unfortunately
https://github.com/QubesOS/qubes-issues/issues/6581#issuecomment-832121456
is not really helpful: Where is that configuration file? Specifically
/var/lib/qubes/dom0-updates/ does not exist after running the update
command.

So what's the status?

Regards,
Ulrich


The changes consequent on hardening of the rpm update mechanism were
poorly handled.
The changes consequent to upgrading the updateVM to fedora-33 were
warnings, and the solution was signalled in the warning message.
(see 'gpgcheck' in dnf.conf(5) for how to squelch this message)
Very few users seem to have a) read that message, or b) tried to do what
it said.

Sorry, but I feel stupid:
Even after removing any failovermethod line from /var/lib/qubes/dom0-updates/etc/yum.repos.d/* in sys-firewall, those lines were re-added next time when I had run qubes-dom0-update in Dom0. Same for adding localpkg_gpgchgeck.

You have to look at the manpage in the updateVM (since that is where the
warning is coming from) and apply the solution in dom0. This isnt
intuitive unless you know about the Qubes dom0 update mechanism.

It wasn't obvious to me that the command output came from sys-firewall (UpdateVM), sorry.

The comment cited earlier reads: "This is harmless. The fix is simply to delete those lines from the configuration in dom0."

I still feel stupid.

Regards,
Ulrich
