When running sudo apt-get update in Ubuntu 18.10, I get the following error message:




E: Failed to fetch https://apt.dockerproject.org/repo/dists/ubuntu-cosmic/InRelease 403 Forbidden [IP: 99.84.208.113 443]



E: The repository 'https://apt.dockerproject.org/repo ubuntu-cosmic InRelease' is not signed.



N: Updating from such a repository can't be done securely, and is therefore disabled by default.



N: See apt-secure(8) manpage for repository creation and user configuration details.



W: GPG error: http://archive.canonical.com precise Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5



E: The repository 'http://archive.canonical.com precise Release' is not signed.



N: Updating from such a repository can't be done securely, and is therefore disabled by default.



N: See apt-secure(8) manpage for repository creation and user configuration details.




I tried running with the --allow-unauthenticated tag, but got the same error message.
