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?
