Hello I am On Ubuntu’s newest version and my regulate desktop environment is KDE Plasma. however I just updated to Plucky and now I can’t get to KDE plasma. It took me to LXQTe where i was told to pick a windows manager where the only option i saw was ix83. I picked that but can’t get to the terminal from there.
So now I’m in the recovery mode trying to install it but then it says that im missing signed by in the sources list even though I see two signed by in the sources list in the sources list.d file. I don’t really know how I got into this mess as all I did was follow the steps that Ubuntu told me to do to upgrade to Plucky. I am really panicking right now so any help would be greatly appreciated.
Had this happen to two out of the three machines I upgraded. (Been a long time since I’ve had an upgrade not go smoothly.) It seems for some reason kubuntu-desktop is getting uninstalled, and that presumably in turn causes most of KDE to get autoremoved. So the solution is just to install that package. You can do this by ctrl+alt+f3 to drop to a terminal. Depending on your networking setup you might need to learn how to setup networking via cli tools, but in my wired machines things just worked. Reboot after KDE is installed and things should be restored.
This is a known issue and is the reason we have disabled upgrades across Ubuntu for now. Normally we don’t have upgrades enabled on day 1, so this took many of us Flavor Leads by surprise.
Best thing you can do is reinstall kubuntu-desktop and hope for the best. If that doesn’t work, downloading the .iso image and reinstalling is really your only option.
