The build logs here show the same stall measured on maas-samba-ad: a 28.5 MB apt fetch taking 31s and a 12.0 MB one taking 30s, while a 14.1 MB fetch completed in under a second. A fixed cost that ignores size is a timeout, not a bandwidth limit — QEMU's user-mode network advertises IPv6 that does not work, so apt's parallel connections black-hole on it and fall back to IPv4 only when the 30-second timeout expires. Patch the build VM's cloud-init seed from bootcmd, which runs before SSH is up and therefore covers upstream's apt calls too. On maas-samba-ad this took the same 28.5 MB fetch from 31s to 3s; no build has been run here since, and the README says so. APT_PROXY also never worked as documented: a cache cannot see inside a CONNECT tunnel, so repositories must be rewritten to plain http, and Debian 13 keeps the real mirror URLs in /etc/apt/mirrors/*.list behind the mirror+file: method, which the old sed missed. Drop the invented "roughly 700 MB" saving from the README. On maas-samba-ad a fully warm cache was worth about three seconds of a 4m40s build. This image pulls far more from the Proxmox repository, so the cache may matter more here, but that is unmeasured and is now listed as such. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
