This page describes how to set up proposed-migration on a clean system.

Installability checks and autopkgtests

In the simplest case you just want to reproduce the "first stage" of britney2-ubuntu, which checks that -proposed packages were built on all expected architectures, are installable by themselves, issue autopkgtests, collect their test results, and produce a production-like excuses.html and excuses.yaml.

• Check out the code:

  git clone https://git.launchpad.net/~ubuntu-release/britney/+git/britney2-ubuntu britney2-ubuntu
  git clone https://git.launchpad.net/bileto
  cd britney2-ubuntu

  The fetch-indexes script inside the bileto repository downloads the source and binary package indexes to data/<series> and data/<series>-proposed.

• The default ./britney.conf contains the production values for the architecture list, autopkgtest AMQP server (but without the actual password) and swift. For a purely local run you need to install the rabbitmq-server package, either locally or into a container, and adjust ADT_AMQP accordingly; use amqp://guest:guest@localhost or amqp://guest:guest@10.0.3.XXX respectively (this will use the default guest user of RabbitMQ).

• If you care about inspecting the issued autopkgtest requests in the AMQP queues, you need to declare them for a particular Ubuntu series:

  sudo apt install -y amqp-tools
  for arch in i386 amd64 armhf ppc64el; do
      amqp-declare-queue -u amqp://<server IP> -d -q debci-mantic-$arch
  done

  You can skip this step, then the test requests will simply go into the void.
• Download archive indexes for the desired Ubuntu series:

  ../bileto/britney/fetch-indexes mantic

• Run britney for the same series:

  ./britney.py -c britney.conf --series=mantic -v

  You will then have the excuses.* and some other files in output/mantic/.

• The list of issued test requests can be found in data/mantic-proposed/autopkgtest/pending.txt. If you declared AMQP queues above, you can also read/flush them, e. g.

  while amqp-get -u amqp://<server IPP> -q debci-mantic-armhf; do echo; done

Installability checks and autopkgtests against a PPA

This works similarly to the above, except that the PPA is now playing the role of series-proposed. Download and use the britney-indexes-ppa scripts instead and run it with the PPA's archive URL:

wget http://people.canonical.com/~pitti/scripts/britney-indexes-ppa
./britney-indexes-ppa vivid http://ppa.launchpad.net/ci-train-ppa-service/stable-phone-overlay/ubuntu
./britney.py -c britney.conf --series=vivid -v

If you have a PPA which only builds packages for i386 and amd64, you need to run britney's build/installability checks against this reduced list:

./britney-indexes-ppa xenial http://ppa.launchpad.net/pitti/systemd/ubuntu/
./britney.py -c britney.conf --series=xenial -v --architectures='i386 amd64'

Full Ubuntu production setup

The full Ubuntu production setup is done by britney1-ubuntu. This creates the archive index lists, per-series configuration files, calls the first and second stages of britney2-ubuntu, and issues the actual copying of packages from -proposed to -release. It assumes having a local mirror and a helper script promote-to-release which does the actual copying.
