This question already has an answer here:

I got the following message when I tried to open update.

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

Please help me to solve it.

    did you run 'sudo dpkg --configure -a'? – user1974 Apr 3 '11 at 13:22

Run the command sudo dpkg --configure -a in terminal, just like the error message says to do.
