you are missing the file in red above for some reason ?

and probably the rest of the ones that cant be found in your error output , I would apt search for the corresponding packages and reinstall them !

Thanks. Sorry for the ignorance, but what do you mean by apt-search?

[calvertrp]

I have reinstalled everything I think that can impact the screen - all of the Plasma things... I'm just about done. Are there any alternatives? I see liquidshell,etc. but have had problems trying to compile. Any suggestions appreciated. I spent too much time over the past month to do a reinstall...

I am a bit of a novice with Kubuntu. I have a Lenovo 3000 N200 with 2.5GB RAM running Kubuntu 18.04.

2.5GB RAM? Won't that be a bit difficult?

Not easy, but not impossible, and shouldn't have anything to do with the missing Plasma objects.

[calvertrp]

Thanks. It was actually running well until this happened.

Thanks. Sorry for the ignorance, but what do you mean by apt-search?

Look at the man page here

It will give you information about the different "apt" options and context for doing a "search" with the apt tool on the command line.

CUPS printing causing the issue

Finally got things working correctly. Had to do with CUPS printing:

https://superuser.com/questions/1025103/kde-5-plasma-keeps-crashing-and-not-starting-again-no-task-bar-no-right-clic/1221053#1221053

I had to reset the CUPS server config to the default. Now I will work to find out why it crashed in the first place. Thanks to all for your help. It has been a learning experience.
