@IThomeboy80 said in Linux: flatpak vs apt / apt get:
APT is old-school, system-level, and tight. Flatpak is modern, sandboxed, and chunky.
I wouldn't characterize as old-school vs. modern. Flatpak is based on an older technique before things like APT existed. APT and its ilk were designed as a response to the chunky systems of the past allowing for more efficient shared resources and better patch visibility.
