So now I know why I get:
$ curl https://brave-browser-apt-beta.s3.brave.com/brave-core-nightly.asc | sudo apt-key add -

gpg: no valid OpenPGP data found.
I had to uninstall the normal version because of the lack of extensions (and remove residual files manually) and now I can’t install the beta either.
I think I will have to stick to chromium even if I don’t want to.
Seem to to much trouble to get this to work unfortunately. Maybe I will try again and maybe not.
It depends on how long time the page is down.
This really seemed like a really great browser.
