Installed package list empty

[Guest]

I recently installed Kubuntu and after X started up it did an upgrade of dpkg and adept. It worked fine until last night and now when i use aptitude, dpkg, apt-get or adept_manager the installed package list is empty and it wont install any packages because it will "BREAK" my install.

Any ideas as to what may have caused this or how to fix it?

Re: Installed package list empty

Try "sudo apt-get update" and "sudo apt-get upgrade". See what errors that gives.

Also, post (or, preferably, attach) /etc/apt/sources.list.

EDIT: And try these three commands:

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