Comment 23 for bug 147429

Before rebooting, saw in adept that many packages were broken. I tried to reload and update through adept, but, after a while, adept crashed.
I finished the job with the following:
sudo rm /var/lib/dpkg/lock
 sudo rm /var/cache/apt/archives/lock
 sudo apt-get install
sudo dpkg --configure -a
sudo apt-get update
sudo apt-get upgrade

(I'm not sure on the exact sequence I used on the above for all this post).

I rebooted
Gutsy works...
