Could_not_get lock_var_lib_dpkg_lock_frontend.md

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?

This may happen if

'Synaptic Package Manager' or 'Software Updater' is open.

Some apt command is running in Terminal.

Some apt process is running in background.

For above wait for the process to complete. If this does not happen run in terminal:

sudo killall apt apt-get If none of the above works, remove the lock files. Run in terminal:

$ sudo rm /var/lib/apt/lists/lock
$ sudo rm /var/cache/apt/archives/lock
$ sudo rm /var/lib/dpkg/lock*

then reconfigure the packages. Run in terminal:

$ sudo dpkg --configure -a
$ sudo apt update
