Public bug reported: I manually added a repository to install a program (brave-browser). After testing for a while I decided the browswer does not suit my needs and did "sudo apt purge brave-browser", then "sudo apt autoremove".
Expected result: my system works as before, just without brave-browser. What happened: "sudo apt autoremove" deleted the keyring of brave- browser, but left the file /etc/apt/sources.list.d/brave-browser- release.list Subsequently "sudo apt update" throws these messages: "W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://brave-browser-apt-release.s3.brave.com stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A8580BDC82D3DC6C W: Failed to fetch https://brave-browser-apt-release.s3.brave.com/dists/stable/InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A8580BDC82D3DC6C W: Some index files failed to download. They have been ignored, or old ones used instead." Uninstalling a program should keep the keyring if it is needed to verify repositories. There could be an option to remove both (though I think removing the repo while keeping the keyring would not return errors).
