Updating problem

Buzz1

Problem upgrading from 16.04 to 18.04. Download went good but it would not install completely I received a message that said that I needed to remove "shim for systemd" before it would continue. I searched & found said item tried to remove it but it wouldn't remove. So now I guess I don't have a complete 16.04 or 18.04. What do I do now?

To uninstall just systemd-shim package itself from Ubuntu execute on terminal:

$ sudo apt-get remove systemd-shim

To uninstall the systemd-shim package and any other dependant package which are no longer needed on Ubuntu.

$ sudo apt-get autoremove systemd-shim

If you also want to delete configuration and/or data files of systemd-shim from Ubuntu then this will work:

$sudo apt-get purge systemd-shim

To delete configuration and/or data files of systemd-shim and it's dependencies from Ubuntu then execute:

$ sudo apt-get autoremove --purge systemd-shim

May be this will help you..
