Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

Typically will get this if another process is running similarly..

Example; Synaptic is open/launched which you needed to authenticate then have tried running updates..

Close out any other open applications then try updating.. Or could reboot (will close any open apps) then once logged back in try updating 1st...
