Ubuntu – Kubuntu 16.04 Plasma can not start after fresh install


I have made a fresh install of Kubuntu 16.04 via USB stick. The sha256 checksum of the USB stick matched the one on the download page. All installed packets have their most recent version. I have a AMD A10-7850K Radeon R7, 12 Compute Cores 4C+8G so I don't have a separate graphical card. On Kubuntu 14.04 I use the flgrx driver but this is no longer available on 16.06.

After I entered my password the blue progress bar reaches its end, but nothing happens anymore for 30 seconds. Then I get a pop-up with following message: "Plasma can not start. All shell packets are missing. This is related to the installation, please take contact with your distribution." (translated myself from Dutch). Then I get a black screen.

When pressing Ctrl + Alt + Delete I get the option to log out or to reboot.

Note: I have seen posts of other people having the same problem on other forums

  • The problem seems to be that the Dutch translations (kde-l10n-nl) of KDE conflict with plasma-desktop. Forcing the reinstallation of plasma-desktop in a TTY fixed the issue. You don't have to reinstall kubuntu-desktop for this to work:

    apt-get install --reinstall plasma-desktop 
    apt-get -f install
