To use our repositories, follow the instructions below: Set up the APT configuration and import our signing key.


This is our main repository which contains our core packages.

Set up a file at /etc/apt/sources.list.d/bunsen.list with the following contents:

deb http://pkg.bunsenlabs.org/debian bunsen-hydrogen main


This is an auxiliary repository containing packages backported from Debian testing and imported from Ubuntu.

Set up /etc/apt/sources.list.d/bunsen-jessie-backports.list with the following contents:

deb http://pkg.bunsenlabs.org/debian jessie-backports main

The backports repo’s packages will have a pin priority of 100, so regular jessie packages will continue to take precedence until you explicitly install a backported package.

To upgrade a package to its backports version, target the backports distribution as follows:

sudo apt-get -t jessie-backports install ${PACKAGE_NAME}

Subsequent package upgrades will be installed from the backports repo or the regular repository, whichever package version is higher.


This repository contains some packages built for Debian testing and unstable and is not part of BunsenLabs. See the package list here.

deb http://pkg.bunsenlabs.org/debian unstable main

Source archives

Package sources may be retrieved using the apt-get source command. To be able to do so, duplicate the lines in your .list files and change the archive type to deb-src.

Access via HTTPS

You may change the http:// prefix in your BL repository URLs to https:// in order to access the repositories using an encrypted connection. Before setting this up, ensure that the package apt-transport-https is installed on your system. The package is part of the BL standard installation.


We currently operate two repository mirrors. If you specify the host pkg.bunsenlabs.org in your APT configuration, you will be redirected automatically to the preferred server based on your IP addresses geolocation:

If you get redirected to asia.pkg.bunsenlabs.org but notice that your ISP has a faster route to the EU server than the Singapore one, put eu.pkg.bunsenlabs.org into your APT configuration in order to opt out from the redirect. Similarly, users in Europe, the Americas or Africa for whom asia.pkg.bunsenlabs.org is faster should switch to that mirror.

Signing key

The preferred method for installing our archive key on your system is using the provided keyring package.

Keyring package

Download the latest .deb keyring package and install it:

wget https://pkg.bunsenlabs.org/debian/pool/main/b/bunsen-keyring/bunsen-keyring_2016.7.2-1_all.deb
sudo dpkg -i bunsen-keyring_2016.7.2-1_all.deb
sudo apt-get update

Alternative method

Fetch and verify the repository’s signing key:

wget https://pkg.bunsenlabs.org/BunsenLabs-RELEASE.asc
gpg --with-fingerprint BunsenLabs-RELEASE.asc

The key’s fingerprint as displayed by gpg should be identical with the following hexstring:

3172 4784 0522 7490 BBB7 43E6 A067 3F72 FE62 D9C5 

If that is not the case, you have got the wrong key. Use a safe, non-intercepted internet connection in order to retrieve the correct key file.

Finally, add the key to APT and update the package index:

sudo apt-key add BunsenLabs-RELEASE.asc
sudo apt-get update

You may now install bunsen-* packages provided by the repository.
