Done E: The repository 'https://deb.debian.org/debian-security testing/updates Release' does not have a Release file. 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.
Unable to download the Release file, this is an inevitable result, because the correct path should be http://deb.debian.org/debian-security/dists/testing-security/Release It should be "testing-security" instead of "testing". Other releases do not have this problem, only testing-security and bullseye-security have "-security" suffix.
