I Upgraded From 11.10 to 12.04 but as I left the computer on for the download the power supply was cut down by a power breakdown so when i turned on ubuntu it said there was a partial upgrade and there was this error and they told me to do this

sudo apt-get install -f

and after that the upgrade manager started installing 12.04 and when it was done and i restarted it was odd like this was like a in between

i couldnt resize the launcher tomboy and banshee are still here the hud is there

so now im stuck between two versions

please help me out of this mess

What was the output of that command you entered? After the command, did you do sudo apt-get update && sudo apt-get upgrade? – Jjed Apr 28 '12 at 23:02

I was having the same problem. The issue may have been caused by a custom unity instances, I tried reverting but that did not really help. So I ended up sudo apt-get install -f which appeared to have fixed the issue.
