You can’t. Endless OS is built around the Flatpak technology to provide it’s application stack. You have multiple choices:

  • Build a Flatpak of the application you need and publish it to Flathub
  • Use toolbox to run a instance of Fedora inside EOS (hint: toolbox create, then toolbox enter)
  • Use Podman directly to run any Docker provided Distribution image (like Ubuntu) in EOS. This one will give you the commands you are used to, like apt. See Running Ubuntu with Podman for further details
