Bug Description

I am trying to update the Ubuntu system from the upgrade icon , and I get the followingfrom the Package manager

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.

Hovering over the icon shows that there is an error: BrokenCount>0

In a terminal, running dpkg--configure-a gives me "dpkg: requested operation requires superuser privilege".

Not sure now - how do I get superuser privilege?
typing 'sudo apt-get remove interchange* ' in the command line gives the same response
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.

Thanks for the bug report.

The sudo command gives you superuser privileges. Please try:

sudo dpkg --configure -a

Does this fix the problem?

Yes, this seems to have fixed the bug - at least, it seems to have, as the responder hasnt responded back. Nevertheless, the support tracker would be more appropriate.
