my version of blender is 2.69, Ubuntu is 13.10, Processor i7 with Nvidia 640 Graphic card. i was running Windows,but changed my mind and want to use Linux, i just installed Ubuntu first time today morning, and whole day i had been searching net to install blender, i really don't know any thing about Linux , but i did install and followed as bellow found in the forum.

sudo add-apt-repository ppa:irie/blender 
sudo apt-get update 
sudo apt-get install blender

second command gives some error, as you can see i pasted here, but third one went ok and run well, after getting DONE message, i try to go to Dash Home and run from there, but as soon as i click on blender icon, just dash Home disappears and nothing happens, same as before Please help.

So the question is ... "is another process using it?" – Rinzwind Nov 12 '13 at 22:25
    
What is the output of ls -l /var/lib/apt/lists/lock /var/lib/dpkg/ /var/lib/dpkg/lock /var/lib/apt/lists/? – Braiam Nov 12 '13 at 22:42

Reboot your system, then after you've logged in open a terminal and type:

sudo apt-get update

Then:

sudo apt-get install blender

If it still doesn't work then type:

sudo apt-get purge blender

Then:

sudo apt-get install blender

Your first step is exactly what @shams is trying to do, but fails - so this is not really an answer. – guntbert Nov 13 '13 at 20:56
    
Good point. But it would seem that apt-get is "temporarily" unable to do it's job. You will also note that my first step is actually "Reboot your system". Having had a lot of apt experience, I could have told him how to fix it without rebooting his system, but he said "i really dont know any thing about lunix". So I figured that he would find it simpler to reboot his system, then do some other sophisticated thing. – Christopher Nov 14 '13 at 0:32
