Caching proxy for Debian and Ubuntu package downloads (apt). The first machine that installs a package fetches it from the internet; every other machine gets it from your server. A maintained replacement for apt-cacher-ng: same port 3142 and the same client settings, so existing clients keep working. Checks every file against the repository's signed index, and keeps serving cached packages when a mirror is slow or down. Clients: put Acquire::http::Proxy "http://SERVER-IP:3142"; into /etc/apt/apt.conf.d/01proxy. HTTPS repositories are not cached unless their sources line is changed to http://HTTPS///host/path. The config is written to /config/config.toml on the first start; edit it there and restart. The status page and Prometheus metrics are on port 6789.

Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.
