From Wikitech

releases.wikimedia.org hosts software releases (primarily packaged as tars). Currently served by releases1003 (standby: releases2003) (formerly: releases1001/releases2001/releases2002/releases1002) behind ATS through the DNS record 'releases.discovery.wmnet'.

Debian repository

Upload a package

On releasesX002:

cd /srv/deployment/parsoid/deploy/
dpkg-buildpackage -b
deb-upload ../parsoid_0.1.12_amd64.changes

Alternatively, build locally and copy .changes and .deb to releasesX002:

scp parsoid_0.4.1_* deploy1001.eqiad:/tmp
deb-upload /tmp/parsoid_0.4.1_*.changes

Check the repository: https://releases.wikimedia.org/debian/

Use the repository

Import the repository gpg key:

sudo apt-key advanced --keyserver pgp.mit.edu --recv-keys AF380A3036A03444

It should say:

gpg: key AF380A3036A03444: public key "MediaWiki releases repository <wikitech-l@lists.wikimedia.org>" imported
gpg: Total number processed: 1
gpg:               imported: 1

Add the repository:

sudo apt-add-repository "deb https://releases.wikimedia.org/debian jessie-mediawiki main"

Add a distro

If you need to add a new distro version, 238348 shows how 'jessie' was added in addition to trusty.

238525 shows how the default was switched.

Running reprepro commands

When running reprepro commands for general purpose ops tasks, use the "reprepro" user (e.g. sudo su -c /bin/bash reprepro) To run reprepro command you also need to run

 export REPREPRO_BASE_DIR=/srv/org/wikimedia/reprepro

GPG operations

The private gpg key used by reprepro to sign distribution files lives in private.git, the public keyring lives in the public puppet repo, both are installed by puppet on the relevant machines.

Generate a new key

It might be necessary to generate a new key, it can be done by creating a temporary "gpg home", generate a new key, and replace the secure keyring in private.git, as follows:

# install -d -m 700 gpg_releases
# gpg --homedir gpg_releases --gen-key

You need a user ID to identify your key; the software constructs the user ID
from the Real Name, Comment and Email Address in this form:

# mv gpg_releases/secring.gpg /srv/private/releases/files/secring.gpg
# cd /srv/private/releases/files/ && git commit secring.gpg

The public keyring pubring.gpg must be updated in the public puppet repo at modules/releases/files. When updating the public keyring, import it in your local machine and send the public key to keyring servers with gpg --keyserver hkps.pool.sks-keyservers.net --send-keys KEYID.

Also remember to delete gpg_releases temporary directory once done.

Refresh signatures

It is sufficient to ask reprepro to export its files again once the new keyrings are in place (as user reprepro! see above):

cd /srv/org/wikimedia/reprepro
reprepro -v export jessie-mediawiki
