Redis apt-get update keeps failing with 403

After following the guide from https://redis.io/docs/install/install-redis/install-redis-on-linux/

apt-get update keeps failing with the errors:

E: Failed to fetch https://packages.redis.io/deb/dists/horus/InRelease  403  Forbidden
E: The repository 'https://packages.redis.io/deb horus InRelease' is not signed.

the command in the tutorial does not work with some ubuntu based distros. replace $(lsb_release -cs) with your actual ubuntu release code name
