I try to execute the command sudo apt-get update; sudo apt-get --reinstall software-center but the below response is follow:

W: GPG error: http://private-ppa.launchpad.net trusty InRelease: 
   The following signatures couldn't be verified because the public key
   is not available: NO_PUBKEY E131728675254D99
E: Command line option --reinstall is not understood

First: I remove "View File" from Software Ubuntu Center after which my Software Ubuntu Center deleted as well.

How can I reinstall my Software Ubuntu Center?
