[sph0600069]

When clicking on the Install Updates button a window appears saying:

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

When trying to run the command through the terminal superprivilege is riguired and I don't know hoe to continue since I am new to ubuntu

Thanks in advance

First close the updater program. Then go to applications > accessories > terminal
in the terminal type in:

sudo dpkg --configure -a
then try running the updater again.
