KDE's Applications System Muon Package Manager

Manage applications and libraries installed on your system to the package level. Search, install and remove packages and inspect their versions and their dependencies.

Note: this does not include applications distributed through Snap or Flatpack. You may prefer Plasma-Discover, if what you are looking for is a Software Center.
