updating CentOS-7 templates

[Achim Patzner]

I just updated my CentOS templates (with hundreds of packages being upgraded) which seems to have messed up the X environment sufficiently; did that only happen to my local generated templates or is that worth reporting an issue?

Yes, mine happened too.

Post error log about /var/log/Xorg.0.log in centos-7 template.

In dom0, use sudo xl console (insert centos vmname here)to access centos7 vm

I did that; that's why I know that there was X11 breakage.

So: Which packages (of the few millions) is the one to back out or what
would have to be added again?

I just downgrade these packages upgrade on centos-7,
xorg-x11-server-{Xorg,common}-1.20.1 back to
xorg-x11-server-{Xorg,common}-1.19.5 and now qubes-gui-agent seems
working fine with it and I can use back my centos-7 as usual. Since
yum info doesn't provides much what's behind the qubes-gui-agent xorg
version range support like apt shows do, so not sure in what extend to
see it as the future upgrade too! New qubes-gui-agent is needed here
before upgrade both `xorg-x11-server-*` packages on centos!

Hope this help!

Thank you.

Finding the right point to get back to was not trivial -- I did yum
downgrade of these packages but mine were at 1.20.1-5.1 and successive
downgrades using "yum downgrade" brought them to 1.20.1-5, then -3 (and
the I got bored by that game).

So does anyone reported this issue to qubes-issues?

Yes (https://github.com/QubesOS/qubes-issues/issues/4646). I'm on it.

[Frédéric Pierret (fepitre)]

A PR is opened. Waiting Marek's approval. It was related to ABI version requirement not done in the qubes-gui-agent-linux. Between xorg 1.19 and xorg 1.20 the ABI version changed from 23 to 24 so xserver was refusing to load the qubes driver.

Best :)

Just keep in mind more or less the same happens if you
transmongrify a Debian template into a Kali following
https://www.qubes-os.org/doc/pentesting/kali/ which is a
warning that there are problems ahead as soon as Debian is
getting its collective ass far enough off the ground to
update X.

As Frédéric says, we're working on this so that by the time buster
comes in there will be a fully working solution out the box. It's to be
expected that there will be breakages in Debian if you move to the
testing version.
