Doesn't quite fix it for me. Purging and reinstalling snapd had no effect.
~/.local/share/plasma already had one thing in it, so I created a variety of new links into /usr/share/plasma/*. That gave me a KDE splash screen, the popup about plasmashell being missing went away, and the crash report dialog was for baloo-file instead of krunner. Still no taskbar, widgets, wallpaper, etc. Creating a link for /var/lib/snapd/desktop/plasma or making the link and purging and reinstalling snapd again (the link survived the purge) had no effect. So I still get to go through the same workaround thunderbird>chromium>konsole>teamviewer>plasmashell. After doing all this, the second instance of KDE lost its taskbar. Had to create it again from the right-click menu on the desktop. The new one looks different, so perhaps it was previously loading the 15.10 version somehow. Also, when the second instance of X starts, the first thing that appears is the login screen, which looks like the Kubuntu 15.10 version. When I lock the screen, I get the 16.04 screen locker. The former displays the time in a localized format based on the physical location of the computer (China), the latter displays the time using the system language/localization (Canadian English). So I'm wondering if something moved around between the two versions, but without updating an important config file somewhere. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576500 Title: Plasma fails to load: "all shell packages missing" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plasma-desktop/+bug/1576500/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
