Hi,
Here what I have :
sudo apt update
Ign:1 http://security.debian.org/debian-security green/updates InRelease
Err:2 http://security.debian.org/debian-security green/updates Release
404 Not Found [IP: ....]
Reading package lists... Done
E: The repository 'http://security.debian.org/debian-security green/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.
Can you help to solve this problem
