I am trying to update my software using update manager however I get the message:
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.
When I try to run dpkg --configure -a in terminal I get the following message dpkg: requested operation requires superuser privilege
I have no idea what this means as I am the only registered user on this computer - Help???
