This cropped up somewhere during the process of installing an nvidia driver (310.32) for my graphic card. Whenever I clicked on the Ubuntu Software Center icon on the launcher, it seemed to work (animation on icon to show that it was starting), and then nothing. So I did the first stupid thing, I tried to remove and reinstall the Software Center; apparently, the remove didn't work properly, so I tried again. Here's the terminal session:
parth@Gladoss:~$ sudo apt-get remove software-center Reading package lists... Done Building dependency tree Reading state information... Done The following packages will be REMOVED: software-center 0 upgraded, 0 newly installed, 1 to remove and 304 not upgraded. 1 not fully installed or removed. After this operation, 4,485 kB disk space will be freed. Do you want to continue [Y/n]? Y (Reading database ... 176079 files and directories currently installed.)

Let me know how I can properly remove and reinstall the program. Thanks.
EDIT: command sudo apt-get update comes to a stop with error message (terminal)
W: GPG error: ppa.launchpad.net quantal Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 4F191A5A8844C542
EDIT: Tried the commands: (i)sudo rm /usr/share/app-install/menu.d/featured.menu result : directory does not exist. (ii)sudo rm -rf /usr/share/app-install/menu.d/featured.menu result : nothing. Terminal just gets ready to accept new line. Further, I tried "sudo apt-get install software-center". Same error message as original post.
EDIT: sudo apt-get --reinstall install software-center returns

EDIT : I figured something was wrong with the dpkg, I googled that. Some commands I tried afterwards.
parth@Gladoss:~$ sudo dpkg --audit The following packages are only half installed, due to problems during installation. The installation can probably be completed by retrying it; the packages can be removed using dselect or dpkg --remove: software-center Utility for browsing, installing, and removing software

Removing software-center ... dpkg: error processing software-center (--remove): unable to securely remove '/usr/share/app-install/menu.d/featured.menu': Not a directory Errors were encountered while processing: software-center
EDIT : sudo dpkg -L software-center brings up a whole lot of files; including /usr/share/app-install/menu.d/featured.menu If it's being shown here, how is it that a recursive force remove ignores it? Are their any other commands (not related to rm) which might work?
