Software Updater broken on 16.04.x

[Ralf Mardorf]

It's overkill, but consider to do it anyway:

1. Reboot

2. Open a terminal and run
   
   sudo apt autoremove

   sudo apt update
   sudo apt full-upgrade

   sudo dpkg --configure -a
   sudo apt --fix-broken install

   sudo apt autoremove

   sudo apt update
   sudo apt full-upgrade

   sudo apt autoremove

   sudo dpkg --configure -a
   sudo apt --fix-broken install

   sudo apt update
   sudo apt full-upgrade

   sudo apt autoremove

3. Reboot

4. Open a terminal and run

   sudo apt update
   sudo apt full-upgrade

   sudo apt autoremove

Is still anything fishy?
