Description Ian Laurie 2020-11-07 06:20:21 UTC

Description of problem:
Rawhide (fc34) had non-functional networking in a VirtualBox VM after a routine upgrade using dnf.  

After many hours of selective installing using a working backup VM and a lot of cloning, I was able to isolate the problem to glib2.

Version-Release number of selected component (if applicable):
works ~ glib2-2.66.2-1.fc34.x86_64
breaks networking ~ glib2-2.67.0-1.fc34.x86_64

How reproducible:
100% reproducible.

Steps to Reproduce:
1. Run updates which installs glib2-2.67.0-1.fc34.x86_64

Additional info:
(1) I am running Rawhide Xfce and if I block glib2 with a --exclude=glib2* I can run updates and networking is fine.  To be clear, as of the moment of writing this, I am 100% up to date with all updates EXCEPT for glib2.  If I install glib2 networking is non-functional.

(2) This is an issue for [at least] MATE and Xfce Rawhide.

(3) For reasons I cannot explain Workstation (GNOME) does work with glib2-2.67.0-1.fc34.x86_64, but MATE and Xfce do not.

My Xfce installation was on a VM co-resident with MATE.  MATE was installed first then Xfce was installed.  I was using Xfce when drilling down to isolate the problem to glib2.

However it looks like building a fresh Xfce only install from:

    Fedora-Everything-netinst-x86_64-Rawhide-20201103.n.0.iso

Does work with glib2-2.67.0-1.fc34.x86_64.

However building a fresh MATE only system with the same ISO as above does not work.

So it looks like the issue is possibly with MATE only, and not Xfce after all, although a system with both on it does have the problem.

Latest compose in:

   Fedora-Everything-netinst-x86_64-Rawhide-20201108.n.0.iso

Seems to have fixed the issue in that freshly built MATE systems have working networking now.
