That apt command isn't valid. "apt upgrade" does not take package names as additional arguments. It upgrades ALL the packages (except the ones it can't). If you want to upgrade a single packge, use "apt[-get] install pkgname" and note that this may mark the package as manually installed, if it's not already.
