I set up the Brave repository pointing to AWS. However, this is what apt-get update tells me:
W: The repository ‘https://s3-us-west-2.amazonaws.com/brave-apt stretch Release’ does not have a Release file.
N: Data from such a repository can’t be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch https://s3-us-west-2.amazonaws.com/brave-apt/dists/stretch/main/binary-amd64/Packages 403 Forbidden
E: Some index files failed to download. They have been ignored, or old ones used instead.
If one goes to that url using a browser one also gets a ‘forbidden’ result.
Seems the release file is the problem. Most likely others will have this problem, too.
