  • I had the exact same problem. Turns out the reason was that I had removed a couple of packages (evolution-data-server and evolution-data-server-common) and that caused apt to also remove key desktop packages.

    To fix it, I booted into recovery mode, then chose Enable network. After that, Drop to root shell prompt.

    Then reinstalled the desktop packages with apt install ubuntu-desktop

    That's it!

    When the installation completed, I rebooted and everything went back to normal.
