I am getting the following error message. Please help

$sudo apt-get install firmware-b43-installer
[sudo] password for sophon: 
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?

In terminal run the following:

sudo rm /var/lib/dpkg/lock

This will remove the lock in dpkg. Now run:

sudo apt-get install firmware-b43-installer

Might be you have opened ubuntu-software-center or synaptic or some other installation program, and thats why you are getting this error message.
