Issues installing Erling using apt (Ubuntu 20.04)

Hi!

We've had issues for the last couple of days regarding installing Erling via apt. I can run apt update with all of our other repos, but when I add the file /etc/apt/sources.list.d/erlang_solutions_repo.list , and the run sudo apt update, I get this error:

E: Some index files failed to download. They have been ignored, or old ones used instead.

I have triple checked ownership of files, tried to run apt-get clean, etc etc, nothing works. The exact same setup (Ubuntu 20.04) worked on the 11th of November.

Has something on your side changed since then?

Kind regards,
