I can't update on Kubuntu 18.10. I have 20 packages, when updating from GUI i get: The PackageKit Deamon has crashed

From terminal: sudo apt-get update && sudo apt-get upgrade -y I get:

E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

I tried this without luck: https://itsfoss.com/could-not-get-lock-error/comment-page-5/

The day after i get:

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

Running: sudo dpkg --configure -a

I can't run: sudo dpkg --configure -a I get: dpkg: error: dpkg frontend is locked by another process

lsof /var/lib/dpkg/lock 

everything is dead.

I believe I have to reinstall a new lock, I don't know how to do so?

sudo touch /var/lib/dpkg/lock

not working.

I entered terminal as root via restore mode by holding shift down under startup and rebootet. sudo dpkg --configure -a worked from terminal afterwords.
