I got this:

$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
$ flatpak remote-ls flathub
error: GPG verification enabled, but no summary signatures found (use gpg-verify-summary=false in remote config to disable)
$ flatpak remotes
Name              Options             
eos-apps          system              
eos-external-apps system,no-gpg-verify
eos-runtimes      system              
eos-sdk           system              
flathub           system              
gnome             system


$ flatpak remote-delete flathub
$ flatpak remote-add --no-gpg-verify flathub https://flathub.org/repo/flathub.flatpakrepo

After this I can list all packages from flathub:

$ flatpak remote-ls flathub

Endless now comes with Flathub enabled by default so all of the latest apps should now show up automatically in the Endless App Center when you update to the latest version of Endless OS.
