Why cant I install applications? on Add/Remove Applications
 

When I try to install a application on Add/Remove... from the Applications menu and I confirm the install I get this error message:


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



"


Please help.

"...you must manually run 'dpkg --configure -a' to correct the problem."

Did you try doing what the error message suggests?

sudo dpkg --configure -a

may be better
