If you're trying to build VyOS ISO image with the usual way you may see following errors:
E: Failed to fetch http://dev.packages.vyos.net/repositories/equuleus/dists/equuleus/InRelease 403 Forbidden [IP: 104.18.30.79 443]

You may also see Sorry, you have been blocked if you try to visit these links, but you aren't blocked - everyone
is blocked. This is due to change in VyOS policy
where they don't offer their dev.packages.vyos.net/repositories for public anymore. This change applies only to
stable branches (like 1.3 equuleus/1.4 sagitta), you can still build current/development branch as usual with
dev.packages.vyos.net/repositories.
