The package pool was committed but the installer still stopped at "no local
package repository": it requires the compiled bundle (Packages, Packages.gz,
packages.lock.tsv, SHA256SUMS), and building that had never run.
The bundle
- 1321 packages, 884 MiB, Ubuntu 26.04 amd64, built with apt-ftparchive on the
fleet's own release so the closure matches the devices.
- built/pool/ is gitignored: those .deb files are already tracked once under
provisioning/offline-repo/packages/, and the same ~890 MB does not need a
second path. What the installer reads from the bundle is the index.
- The output directory is chmod 0755: mktemp -d created it 0700 and left it
so, which made a valid bundle unreadable to the installer's probe.
dpkg-deb output was parsed wrong in four places
- `dpkg-deb -f <file> Package Version` prints "<Field>: <value>", and the
callers kept the whole line, so the value carried its label. build-index.sh
therefore accepted no package at all and reported an empty pool;
add-packages.sh rejected every real .deb as an invalid name, missed version
conflicts, and copied a duplicate; build-offline-repo.sh never matched a pin.
- The test suite could not see any of this: its dpkg-deb stub emitted bare
values. The stub now prints the labels exactly as the real tool does, which
is what surfaced the remaining three sites.
Tests
- The secret scan covers the files we author, not apt-ftparchive's index over
third-party packages: polkit's own description reads "...asked for their
password:", which is prose in the packages, not a leak. Any secret reaching a
manifest, README or tool is still caught.
- The "test build must not touch the bundle" assertion now compares the
directory before and after instead of demanding it be empty, so a
maintainer's real build is not reported as test spill.
