I also see this on Silverblue 32.20200310.n.0 (Fedora pre-32) with gnome-control-center-3.35.92-1.fc32.x86_64

BTW: Upstream issue also filed (by Stefano) @ https://gitlab.gnome.org/GNOME/gnome-control-center/issues/906

Comment 2 Kalev Lember 2020-03-19 11:46:29 UTC
I think this is the missing libnm gschema issue that mcatanzaro has been working on.

Michael, did you get any traction with moving the gschema out of nm-connection-editor or should we add back the requires in gnome-control-center?

Comment 3 Michael Catanzaro 2020-03-19 15:23:32 UTC
Thomas was working on this. Looks like he's fixed it in rawhide, but not in F32.

Thomas, how about I just have gnome-control-center Requires: network-manager-applet again, but only in F32? That seems simpler at this point than upgrading libnma and network-manager-applet in F32? I'm glad we've got it fixed properly in rawhide, and restoring this little workaround for F32 seems unproblematic to me.

Comment 4 Thomas Haller 2020-03-19 15:49:34 UTC
yes, that's what I said here: https://gitlab.gnome.org/GNOME/gnome-control-center/issues/881#note_732240

Quite possibly, Fedora 32 will also eventually get an update to libnma-1.8.28+ and network-manager-applet-1.16.0+. However, I'd like to first get some feedback that shows that these versions aren't terribly broken (because they bring large changes).
