I am using Ubuntu 11.10. After upgrading, neither software-center nor update-manager would run. I get a segmentation fault when launched from the console.
I can do
sudo apt-get update without problem, but the upgrade does not work neither does the installation of any package i.e.,
sudo apt-get upgrade or
sudo apt-get install emacs simply returns the prompt back and nothing happens.
More exactly :
software-center gives this :
2012-01-30 16:07:17,144 - softwarecenter.ui.gtk3.em - INFO - EM's: 17 15 21 Segmentation fault Nothing else happens then. With
update-manager: Segmentation fault A window flashes and immediately goes away. With
sudo apt-get install emacs and
sudo apt-get upgrade nothing happens with either of these two commands.
sudo apt-get upgrade works well though
