As I mentioned in an earlier post, Ubuntu 9.10 Karmic Koala is still in Alpha.
This is what happens when you sail in uncharted waters:
I applied all of the updates for Karmic Koala and instead of rebooting, the system logged me out, and I was back at the login screen. Neither the mouse nor the keyboard worked anymore, and I assumed it would be alright to simply just hit the reset button - I was wrong.
The hard reboot caused errors on my root and home partitions, and the system could not be booted up. I was presented with a "Unexpected inconsistency: Run fsck manually" error. It was back to the command line.
After spending close to a year in a *hit hole called Fedora, I had become accustomed to the workings of a *hit OS. I call this the typical Fedora experience.
Running fsck on the / and /home partitions solved the problem. :P
