update manager error message

Asked by gregorio Tejedor Delgado on 2008-01-22

I have a update error message E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report. I have read similar questions and answers, but When I run dpkg --configure -a nothing seems to happen.
I only get a next line indication >.
Could someone explain to me (step by step) How to proceed from this point onwards? I am also totally new with Linux (Ubuntu)
Thanks in advance,

When I run dpkg --configure -a nothing seems to happen.

→ you must run it as root - so 'sudo dpkg --configure -a'

Dear Vojtech Trefný,
Thanks for the advice, It is solved now. after doing what you suggested, I got a message that it was processing.
After that I closed the console and tried again to download the updates..... It worked perfectly.
Thanks a lot.


Ps. Do you know what exactly this commandl line does? (does it process still uninstalled programs already on your computer????)
