Could not get lock ?
 
What to do ?
Wait - for what ?

" is another process using it? "

I do not know , if it is what can it be done to stop it ?





Code:
a@a-desktop:~$ sudo apt upgrade
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?
a@a-desktop:~$

Personally, I'd just reboot.

The correct answer is to use tools like fuser and lsof to determine which process is using /var/lib/dpkg/lock-frontend.

Your system is probably doing an automatic search for new updates or possibly doing an automatic update if so configured. Just wait for it to finish.

I second what michaelk said. I have witnessed that a lot of DEs do a check for updates immediately upon login and periodically thereafter.

^ There you are, you don't even need to do it manually, it is automated.
But if you do it manually you must run 'apt update' before 'apt upgrade'.
