Package management systems (PMSs) or package managers (PMs) are collections of software tools that automate, simplify and streamline the processes of software installation, removal, upgrade and configuration. PMSs vary significantly by Linux distribution (LD):
- Arch Linux-based LDs, such as Arch Linux use Pacman.
- Debian-based LDs, such as Debian, Linux Mint and Ubuntu use APT and dpkg.
- Red Hat Linux-based LDs, such as CentOS, Fedora and Red Hat Enterprise Linux use DNF and yum.
- SUSE Linux-based LDs, such as OpenSUSE and SUSE Linux Enterprise use YaST and ZYpp.
