Synaptic Package Manager not working..?

[alexisd]

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


I'm getting that error message when I try to open the synaptic package manager. What do I do to fix it?

thanks in advance

Close synaptic. Then, open a terminal and run

Applications -> Accessories -> Terminal

sudo dpkg --configure -a
sudo apt-get update
sudo apt-get upgrade

Okay but then when i do that it asks me for the sudo password

Use the same password that you log in with.
