Fedora 33 upgrade - cgroup v2 error when running snaps

[var38]

Just upgraded to Fedora 33 and existing snap for Authy fails

WARNING: cgroup v2 is not fully supported yet, proceeding with partial confinement
(authy:39535): Gtk-WARNING **: 06:19:28.150: cannot open display: :0

I tried removing Authy and Snapd entirely then starting over. Reinstall of snapd works fine, from what I see. However, when I attempt to reinstall authy it seems to work but I saw something about “gnome-3-28-1804” but didn’t capture the message. I looked through journalctl and found

“Mounting Mount unit for gnome-3-28-1804, revision 145…”

Fedora 33 is on Gnome 3.38, is it somehow getting the wrong version because this was an upgrade and having a conflict?

Thanks in advance for your assistance

assuming fc33 uses wayland, see:

Apps won't run and crash on gnome/wayland

The fix is now available in groovy-proposed, and will go to updates once it has passed QA: https://launchpad.net/ubuntu/+source/mutter/3.38.1-2ubuntu1 The fix has been merged upstream to the gnome-3-38 branch. So it will hopefully make its way to other distros as they update. Looking forward, snapd is also being patched to give snaps plugging the x11 interface access to the non-abstract sockets: https://github.com/snapcore/snapd/pull/9530 The GNOME devs have indicated that they would like …

(note that the cgroup v2 warning is harmless and has nothing to do with your app not starting)

Thanks for that. Does look like it was related to Wayland - seems the upgrade to F33 reenabled Wayland which I’d disabled previously. Moving back to X11 also cleared up a couple other issues I was having since the upgrade.

Appreciate the quick response.
