pacman-package-manager 6.0.1-4 (s390x binary) in ubuntu kinetic

 pacman is a utility which manages software packages in Linux. It uses
 simple compressed files as a package format, and maintains a text-based
 package database just in case some hand tweaking is necessary.
 pacman does not strive to "do everything." It will add, remove and
 upgrade packages in the system, and it will allow you to query the
 package database for installed packages, files and owners. It also
 attempts to handle dependencies automatically and can download packages
 from a remote server.
