Blender does not start

[Greenality]

Hi,

i uses Ubuntu 12.04.1 LTS, and have used blender with no problems. But for four days it does not start anymore, and I just don't know why. I have to start it with the help of the terminal, but it just shows me some informations i don't understand.

I already asked in some forums and they told me to type this in:

sudo apt-get update 
sudo apt-get upgrade 
sudo apt-get install -f 
sudo dpkg --configure -a

After this I get this:
