I JUST got ubuntu for my pc. I know very little about the program and i have'nt altered anything at at all. But for some reason the ubuntu software center wont open. I dont even get an error message i just click and it wont open. Im running on the latest version of ubuntu. Also the update manager dosnt work but I 'll cross that bridge when i get there. So if you guys know why my ubuntu software center wont open that would be major help. thanks

Try to purge and re-install .

From terminal

sudo apt-get remove --purge software-center
rm -r .cache/software-center
sudo apt-get install software-center ubuntu-desktop
sudo update-software-center

W: Not using locking for read only lock file /var/lib/dpkg/lock E: Unable to write to /var/cache/apt/ E: The package lists or status file could not be parsed or opened. –  Dice Nov 14 '12 at 2:41
    
So you have a general problem with package manager I guess. Is not the software center. Try to close ALL applications and open only a terminal. Write this command sudo rm /var/lib/dpkg/lock and then try again. OR else you have to follow the PackageManager Troubleshooting Procedure –  NikTh Nov 14 '12 at 2:46

The problem for me was the used system icons. The program manager did not start after i took a diverend icon theme. After I set it back to the default icon set the problem was sloved en started just like brand new!
