Housekeeping after the Debian stretch release

The Debian stretch release implicitly inflicts some mandatary (new apt keys!) as well as some minor recommended housekeeping on an existing mini-buildd installation.

So this is what I would recommend you to do -- assuming a basic setup, near to what the wizards would set up automatically.


Given how the configuration currently works (i.e., affecting dependencies when you change things), you might want

  • to stop the daemon before starting your housekeeping
  • and try to get all your changes done in one flow (to minimize the costly "PCA action" on repos and chroots later...)

Update to >= 1.0.30 and run Source wizards

1.0.30 adds wizard-support for new sources now available (like buster, stretch-backports, jessie-backports-sloppy, and also the new Ubuntu release). Obviously not mandatory, but it will really helps in housekeeping.

Please check the home page overview if that version is available for the system your mini-buildd runs on.

With 1.0.30 installed, run (in the admin configuration):

  • Sources:Archives Debian wizard: Will get you (you may want to remove
  • Sources:Sources Debian wizard: Will get you new sources for buster, stretch-backports and jessie-backports-sloppy.
  • Sources:Priority sources Extras wizard: Adds new prio sources stretch-backports and jessie-backports-sloppy.

Existing stretch: Fix apt keys

You will need these two additional keys after stretch=stable:

"CBF8D6FD518E17E1": Jessie Stable Release Key <>
"EF0F382A1A7B6500": Debian Stable Release Key (9/stretch) <>

Add these keys to the AptKeys instances if they are not already there, verify and make them shiny green.

Then, add these two keys to the stretch Source.

See:, debian-archive-keyring package, apt-key.

Existing stretch: Fix release version

Stretch's release version (as configured in the stretch Source) should currently be "STRETCH" or "~STRETCH". Now with stretch released, this must be replaced by the actual release version.

FWIW: This default scheme will put you in the position to distinguish between packages build while stretch was rolling, and after stretch was released, just via the package version -- hinting you on what packages you might want/need to rebuild on the actual finsihed stable release.

To do this, just go the the stretch Source instance, reveal the "Extra" section, and either

  • Recommended: Override with "90" or remove the override string (this let's mbd guess on check, which will lead to "90" for 1.0.x).
  • Override with "9" (this is the new scheme also adapted by Debian backports now, and default in upcoming release 1.2.x of mini-buildd).

Note that using "9" may lead to dist-upgrade issues for packages from, for example, a jessie distribution using "80" -- for packages with otherwise the very same versioning. So only use that if you (understand this and) are up to instruct your repo users on remedies, or if you are using the new scheme consistently already anyway.

Existing stretch: Add new stretch-backports as extra source to your stretch Distribution(s)

This is default when distributions are created by the wizards, so this is recommended.

Existing jessie: Add new jessie-backports-sloppy as extra source to your jessie Distribution(s)

This is default when distributions are created by the wizards, so this is recommended.

Add buster

Be sure to have the new buster Source activated (PCA):

  • Run Repositories:Distributions:Default wizard, which should give you the new Distribution for buster.
  • Add the new buster Distribution to the resp. repositories.

Update chroots

  • Run Chroots:Default wizard (on the backend you are using). Thus should give new buster chroots.

Optionally recreate some or all your chroots

... now that you are at it anyway :).

mini-buildd always keeps the base chroots up to date, so this is actually not strictly really necessary. However ;), as a safeguard against any possible evilry that might have crept into your existing base chroots, you might want to do this; there are no drawbacks, it just take some time.

Just Remove the chroots you want to recreate, and then run PCA on it again.

Restart Daemon, Final Touches

Be sure everything you want is finally "green" in the admin config overview (merciless run "PCA" on everything that's not ;).

Then, don't forget to restart the Daemon once (either by clicking an stop/start as admin in the web app) or just by just restarting the service:

# service mini-buildd restart

-- else you might experience subtle misbehaviours ;).

In case you have mutiple instances, you unfortunately need to do these manual updates (or at least parts of it) on each of these.

In case you created new Distributions, you should build new keyring packages (and migrate the new packages up to stable, at least for new Distributions).
