Dear Maintainer, - What led up to the situation? While reading the apt-secure manual (man apt-secure), I came across a section that refers users to more information at the following link under the title *Debian Security Infrastructure*: https://www.debian.org/doc/manuals/securing-debian-howto/ch7 - What exactly did you do (or not do) that was effective (or ineffective)? I attempted to visit the above URL to learn more about Debian's security infrastructure. However, the link appears to be broken or no longer exists. - What was the outcome of this action? The page results in a 404 or redirect with no relevant content, making the documentation reference unhelpful. - What outcome did you expect instead? I expected the link to lead to a valid and relevant page about securing Debian systems, especially one related to apt security and verification mechanisms. It would be helpful if this outdated link could be either updated to point to a currently valid resource or removed if no longer applicable. This would ensure the documentation remains accurate and useful. Thank you for your work on Debian and maintaining apt. Kind regards, Arman Tahery
