Found existing questions with matching headline are dated deep in the past so me considers them as unrelated.

One of first operations for Ubuntu machine here after upgrade to Bionic B. completed (from 16.04.x LTE) was to start sudo apt-get autoremove. Unfortunately that operation resulted in GUI typical for Beaver B. been gone, I am no GNOME nor Desktop env. expert, so hard for me to use here proper technical terms. Bionic B. looked like be free from GNOME and that stack.

Today, few weeks later, autoremove is pending again as storage space goes to limits due to numerous and frequently kernel updates. I afraid if I do it now again Bionic B. typical look&feel goes away. Attached is picture which lists items autoremove attempts to delete. Can one see here suspicious points?

  • You have 2 problems. To remove old kernel see askubuntu.com/questions/2793/… and otherwise clean your hard drive, logs perhaps. I would not use autoremove to free space. You might break kubuntu but you could try booting to recovery mode, run autoremove, and then re install kubuntu-desktop

I had a related problem, see "dist-upgrade wants to remove kubuntu_desktop". Based on some research (and help on this forum), I see two possible reasons for your problem.

1) Maybe the KDE gui is not listed as your preferred desktop environment and there is no other reason why it should be kept on your system. You can check this by issuing ls /usr/share/xsessions and see what your system is currently using as your desktop. If this is not plasma.desktop, you might just want to manually install it by saying sudo apt install kubuntu-desktop. On the other hand, if you want to use gnome, it is maybe ok that your system wants to auto-remove kde?

2) In my case, there was a conflict between a graphics driver component and kde. This might happen if you have installed a proprietary graphics driver, such as fglrx. You might want to check your /etc/apt/sources.list.d for any ppa sources you might have installed (in my case dokomix-ubuntu-fglrx-bionic-bionic.list). If this is the case, you might revert to the native driver and remove the ppa.

There might be other driver updates (or other package updates) that are not compatible with kde and come with another desktop environment - which could lead the the removal of kde. You can check this by doing a sudo apt dist-upgrade and see if there are any packages being held back. These might be the culprit.

  • In context of my latest problems investigations (askubuntu.com/q/1111131/692481) it was needed to conduct autoremove again. This time the start point was OS recovered from backup, backup was generated shortly after upgrade to 18.04 completion. This time autoremove run did not have any negative outcome.
