A Tale of Two (APT) Transports

This post introduces a new custom APT transport that integrates with Cloudflare Access to secure private APT repositories. It details the history of APT, the bootstrapping problem of installing HTTPS support, and the mechanism by which APT transports work. The post outlines the installation of the `cloudflared` executable and the custom `cfd` APT transport binary, and demonstrates how to configure APT sources to use the `cfd://` scheme. It also covers fetching GPG keys over Access and discusses handling Access on headless servers.
