unable to lock

[rhoward]

I am trying to install some upgrades and here is the message I am getting.

E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
I am trying to remove/var/lib/dpkg/lock,because I think that is the source of my problem, but it seems no matter what I try from terminal I cannot remove it. I can't just delete it, it won't let me, I must remove it but how do I do that?
Some help please!!!
Thank you,
R Howard

Hi, before trying to remove the lock file you should make sure that you have no other package managers opened eg synaptic, apt-get, update-manager, dpkg. If none of those are open then open a terminal and type

ps -e this will give a list of running processes check down the list that no package manager is running (synaptic, apt-get, update-manager, dpkg) if there is then you will need to kill the process which you can do with

sudo killall name (replace name with name of process)
if there are no package manager processess running then remove the lock with

sudo rm /var/lib/dpkg/lock
