This repository contains Debian and Ubuntu packages modified for use by Wikimedia as well as packages for Wikimedia-originated projects.
Starting with Debian 9 Stretch, we are using a new repository structure with the following components:
maincontains all the packages that we either create internally or packages that we backport or modify from Debian and which are useful fleet-wide (e.g., Icinga plugins, Cumin, etc.)
thirdparty/hwraidcontains binary-only drivers for RAID management used on baremetal servers only.
- All other components using the
thirdparty/prefix are synchronised from external repositories (e.g.,
thirdparty/k8s(Docker)). Please do not add internally built packages to
- Some packages should not be available fleet-wide, but rather be used in more specific scenarios such as the following:
component/ciprovides co-installable PHP packages that are only necessary for CI
- "contain" specific packages that depend on outdated or backported libraries (e.g. crypto libraries)
- ease migrations and upgrades for certain roles, while leaving the rest of the fleet untouched
You can find a complete list of repository components in our Puppet config
For older Linux distributions like Debian 8 Jessie or Ubuntu 14.04 Trusty, the new repository organization was not applied retroactively due to the extra effort required.
In such cases, internally built packages could be in
backports. If you add new packages, always use
Additionally, third-party packages are not fully split into logical components and they could be in the
thirdparty top-level component as well as in sub-component
If you are updating third-party packages, remember to update either
thirdparty or the
thirdparty/foo sub-component depending on where they were originally located. If you can, a better long-term plan is to update to Debian 9 Stretch.
Finally, Ubuntu 14.04 Trusty also has
non-free. Ignore those and use
For Wikimedia servers and Cloud VPS instances, the repositories are automatically configured via Puppet.
To use this repository from an external host, the following lines need to be present in
## Wikimedia APT repository deb http://apt.wikimedia.org/wikimedia stretch-wikimedia main deb-src http://apt.wikimedia.org/wikimedia stretch-wikimedia main
Use the right distribution, depending on which Debian/Ubuntu version was installed (e.g.
Here is a complete list of all the available sources:
deb http://apt.wikimedia.org/wikimedia trusty-wikimedia main experimental backports deb http://apt.wikimedia.org/wikimedia jessie-wikimedia main experimental backports deb http://apt.wikimedia.org/wikimedia stretch-wikimedia main deb http://apt.wikimedia.org/wikimedia buster-wikimedia main deb-src http://apt.wikimedia.org/wikimedia jessie-wikimedia main backports deb-src http://apt.wikimedia.org/wikimedia trusty-wikimedia main deb-src http://apt.wikimedia.org/wikimedia stretch-wikimedia main deb-src http://apt.wikimedia.org/wikimedia buster-wikimedia main
Additionally, to make sure that the system prefers packages from this repository, and not packages from the origin distributions even if they have a higher version number. For example, this APT source is "pinned" with a higher priority in
Package: * Pin: release o=Wikimedia Pin-Priority: 1001
You can confirm Wikimedia's APT repository is taking preference now by running `apt-cache policy <package>`:
$ apt-cache policy puppetmaster puppetmaster: Installed: (none) Candidate: 4.8.2-5 Version table: 4.8.2-5 1001 500 http://deb.debian.org/debian stretch/main amd64 Packages 1001 http://apt.wikimedia.org/wikimedia stretch-wikimedia/main amd64 Packages
The Wikimedia repository is signed with the
Wikimedia Archive Automatic Signing Key <firstname.lastname@example.org>. This public key must be installed in APT's GPG keyring so it can verify packages successfully.
The key can be retrieved from /Stretch-Key (this key was introduced with stretch and also applies to later distros)
To install it, download the key to
/etc/apt/trusted.gpg.d/wikimedia-apt-key.asc, or on older systems add it using `apt-key`:
# Debian buster or later $ wget -O /etc/apt/trusted.gpg.d/wikimedia-apt-key.asc "https://wikitech.wikimedia.org/w/index.php?title=APT_repository/Stretch-Key&action=raw" # Debian Stretch or earlier $ wget -O wikimedia-apt-key "https://wikitech.wikimedia.org/w/index.php?title=APT_repository/Stretch-Key&action=raw" $ apt-key add wikimedia-apt-key OK
You can also retrieve the key from a Cloud VPS host:
ssh <host> apt-key export email@example.com
