I had some problem with ubuntu software center so i uninstalled it then reinstalled using following command(s) in terminal
sudo apt-get install software-center
And I got this as output:
Package software-center is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'software-center' has no installation candidate
sudo apt-get remove software-center? – geoh Jan 8 at 12:21
