Package: elpa-use-package Version: 2.4.4-1 I am a fun-loving bloke so /usr/games is on my path and pacman (the package) is installed. When emacs is started and elpa-use-package loads and searches for an appropriate value for system-packages-package-manager it finds the executable /usr/games/pacman so the variable gets set to "pacman" instead of "apt".
Waka waka waka.
