You appear to be running Debian 11, but you have a reference to stable-security which is now Debian 12. To fix that, replace stable-security with bullseye-security in /etc/apt/sources.list and files in /etc/apt/sources.list.d:
sudo sed -i.bak s/stable-security/bullseye-security/ /etc/apt/sources.list
sudo sed -i.bak s/stable-security/bullseye-security/ /etc/apt/sources.list.d/*
Then update with
sudo apt update
You should then be able to install samba. You might need to downgrade some packages to their Debian 11 versions, if they’ve previously been updated to Debian 12 versions.
