is a file apparently used to "lock" something to prevent two processes from working against each other. This thread implies that the lock file should ordinarily be absent, yet I see it on my system which is functioning normally. In other words, I'm not quite sure what is going on! If you haven't rebooted your system, please do that & trysudo apt-get update
, thensudo apt-get full-upgrade
