[CRASH] Bad news from my penguin :(

A week ago I tried to upgrade my Ubuntu 12.04 into 12.10. With my slow internet connection, its ran about 24 hours to download the upgrade. After waiting for it, I choose the wrong options about to kill the KDM DAEMON…. anddd its crash. Im so confused about this.

Nothing can restore my linux config :(

finally, I reinstall my linux, and now I try to always backup my installed packages.
