Can you show the complete output of that command? A bit higher up there should be some details on that error. It's best to know the root cause of the problem.

Thanks for your help...
After several tries I found this problem no longer exists... I even don't know how this was resolved....:confused:

I guess one effective way was running the code


sudo apt autoremove
