Yesterday, as is my usual custom, I upgraded my laptop from Fedora 27 to Fedora 28 Beta. I used DNF system upgrade, as I have in the past. The only hiccup was entirely my own fault. I forgot that while I’ve set GNOME to ignore the lid closing to prevent suspension, that setting doesn’t apply during system upgrade. 🙂 Oops.
Used DNF to remove duplicate rpms, reinstalled the new kernel and libwbclient, and corrected GNOME’s right-click behaviour, and all is well.
