How to unlock apt-get?

["Bill.M" <bill3@uniserve.com>]

Hi folks,

I'm having a problem with apt-get. I seem to be locked out of 
/var/lib/dpkg/lock and /var/lib/dpkg when I try to do an apt=get update 
, How can I clear these locks? And if there's another process using apt, 
how can I discover what it is? I've rebooted without success.

E: Some index files failed to download, they have been ignored, or old 
ones used instead.
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?
