Upgrade Failed

[helmsdb]

I'm trying to install an upgrade to Ubuntu - the error message says E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open()failed, please report

I don't know how to run this command manually - how do I get into manual mode?

Hi, do as it says, open a terminal (Applications>Accessories>Terminal) and type

sudo dpkg --configure -a

Thanks - I'll see if that helps!:)

If it does not fix it, post the output to the 'sudo dpkg --configure -a' command so we can see what the problem could be.
