IGWN Debian Repositories

IGWN Software support for Debian is provided by the Max Planck Institute for Gravitational Physics at Potsdam-Golm via a (signed) repository.

Configuring apt

Debian users can configure the IGWN Debian Repositories as an extra package source.

You might need to install ca-certificates and apt-transport-https before

In order to accept the certificate offered by hypatia.aei.mpg.de you may need to install the ca-certificates package. Also, since hypatia insists on using https, the apt-transport-https package has to be installed:

apt-get install ca-certificates
apt-get install apt-transport-https

Download the key file and install into /etc/apt/trusted.gpg.d/hypatia-key.asc or download the key package and install using dpkg -i.

Create /etc/apt/sources.list.d/lscdebian.list with the following content:

deb [signed-by=/etc/apt/trusted.gpg.d/hypatia-key.asc] https://hypatia.aei.mpg.de/debian {dist} lvk

with {dist} one of

  • bullseye,
  • bookworm or
  • trixie.

(Caveat: As of December 2025, bullseye as oldoldstable is being phased out.)

Not all Debian releases are supported for all platforms - while amd64 and arm64 are maintained as much as possible (modulo reported but unfixed bugs), riscv64 and ppc64el are considered experimental and only trixie is available for them.

Once this is configured, run (this may require sudo like the previous steps):

apt-get update

to make the new package source available to APT. (Check for errors and fix them before proceeding.)

To check that this configuration works, you should be able to search for IGWN-internal packages, e.g. lal:

Verify Debian configuration

# apt-cache policy lal
lal:
  Installed: (none)
  Candidate: 7.7.0-1.1+deb12u0
  Version table:
     7.7.0-1.1+deb12u0 500
        500 https://hypatia.aei.mpg.de/debian bookworm/lvk amd64 Packages
