apt-get errors

Hi all,

I recently installed Debian Wheezy on an old Dell Inspiron laptop. It's working pretty well, aside from a few hiccups. One of these happens when updating. apt-get update returns the following errors:

I ran the command again, and got this:

E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/lib/apt/lists/

Is there anything I can do about this?

Thanks.
