> how on earth someone choose rpm over first class Superior Debian package system So, what makes the Debian package system superior? Having built multiple specs in the past, but not any debs, I'm curious. Given that you can often convert debs to RPMs and vice-versa, and can use the different package managers on either type of repository, it's not obvious where one has any specific benefit.
its not that .deb is a better than format than .rpm, but apt is better than yum, as a dependency manager.
Either use separate commands for different actions, or distinguish actions with arguments, but don't do both. E.g. apt-get install, apt list, apt-file update.
