A debian:bookworm workspace job died on `apt-get update`: the mounted sources list carried the Ubuntu entry too, Nexus had auto-blocked archive.ubuntu.com, and apt fails the whole update on one bad source. Three holes, three plugs: - One sources list per INFINITO_DISTRO under compose/package-cache/apt/, selected by the compose overrides. A Debian runner no longer fetches an Ubuntu suite it has no use for. The non-apt distros get an empty file so the bind mount has a source to point at. - autoBlock off. While a remote is auto-blocked Nexus answers `404 Remote Auto Blocked` to every client instead of falling back to the copy it already has cached. - Mirror failover in the frontend. Every apt suite gets a second proxy repo on an independent upstream; a 5xx from the primary re-runs the request against it. Nexus has no group repository type for apt, so the retry lives in nginx. Measured on a live Nexus 3.91.1: dead remote without a cached copy answers 502, with a cached copy 200 regardless of metadataMaxAge. The frontend serves 149 kB of real bookworm `Release` from the mirror repo when the primary is dead, and the new regex locations produce upstream request lines byte-identical to the `rewrite … break` form they replace, including `%3a` epochs in pool paths. INFINITO_CACHE_PACKAGE_APT_LIST is gone; the mount interpolates INFINITO_DISTRO directly. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# Package-Cache Wiring 📦
|
|
|
|
Client-side configuration bind-mounted into the `infinito` runner so that pip, npm, and apt route through the Sonatype Nexus 3 OSS pull-through proxy.

For services, activation, coverage, and operations of the local cache stack, see [cache.md](../../docs/contributing/environment/cache.md).

## Files 📄
|
|
|
|
- `pip.conf`: pip configuration. Mounted at `/etc/pip.conf`. Routes pip through `pypi-proxy`.
|
|
- `npmrc`: npm configuration. Mounted at `/root/.npmrc`. Routes npm through `npm-proxy`.
|
|
- `apt/<distro>.list`: apt sources, one file per `INFINITO_DISTRO`. The matching file is mounted at `/etc/apt/sources.list.d/package-cache.list`. `apt/debian.list` routes apt through `apt-debian`, `apt/ubuntu.list` through `apt-ubuntu`; the pacman/dnf distros get an empty file, because `apt-get update` fails as a whole on a single unreachable source and must not carry a foreign distro's entry.
