I forced an upgrade from kubuntu 12.04 to 12.10 and when booting it sticks on the loading screen. Looking at the boot log shows me that 'Starting K Display Manager' as 'failed'. How can I fix this?

After a bit of hunting around I wasn't able to find what the issue was, but I found that I could log in if I pressed

ctr + alt + F1

This gave me hope that my installation wasn't borked. I found a website that told me to execute this command:

sudo dpkg --configure -a

This did a load of stuff, and at the end told me a few things failed (kubuntu-desktop being one of them), but after a restart my desktop came back.

I hope this helps anyone else having the same issue - if anyone knows why this worked, please explain in the comments of this answer.

Looks like your update process failed in the middle of it (power/network?) –  Karthik T Oct 22 '12 at 7:02
    
"if anyone knows why this worked, please explain in the comments" - or, better yet - propose an edit to the question to improve it. –  Eliran Malka Oct 22 '12 at 7:05
    
@KarthikT I'm pretty sure it didn't power down during the upgrade. –  Martyn Oct 22 '12 at 8:18
