Unable to upgrade Hardy heron 8.04
I'm quite new to Ubuntu , and am having a problem trying to upgrade .
Whenever I try to use the update manager I get a message saying that it is unable to get exclusive lock.
I've tried sudo apt-get purge / clean / install for the apt-get , and the same for aptitude.
All I get when I try this is the following message -
E:Could not get lock /var/lib/dpkg/lock - open ( 11 resource temporarily unavailable )
E: Unable to lock the administrative directory ( var/lib/dpkg) , is another package running ?
As far as I know , no other package is running the update manager
Any help would be very much appreciated

Close Synaptic or other apt-get processes
