'dpkg --configure -a' problem after interrupted update

Asked by igg

My manual update was interrupted and when I try to install something or update 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.

Then I type following command in Terminal (Applications → Accessories → Terminal):

sudo dpkg --configure -a

But I get the following:

nb@nb-lp:~$ sudo dpkg --configure -a
dpkg: failed to open package info file `/var/lib/dpkg/available' for reading: No such file or directory

Please help me!

Usually that's when another app is already using package index.
Please make sure while working in a terminal to close all other package management related GUIs e.g. Synaptic, Update Manager, Software Center ...
