KERN is a bi-annually released set of radio astronomical software packages. It should contain most of the tools that a radio astronomer needs to work with radio telescope data. KERN is based on the latest Ubuntu LTS.
Open up a bug report in our packaging issue tracker. Please make sure that you are running the latest versions of the packages you are using (run apt-get update && apt-get upgrade). Note that a package in an existing KERN release is only updated when there is a dramatically serious problem.
KERN means 'core' in Dutch and Afrikaans.
We have a bleeding edge development repository (KERN-dev) that will be updated with the latest packages. Ideally every half year we will freeze this repository and do a KERN release. This release will then only contain critical bug fixes but not functional changes.
we have prepared easy-to-use base docker image which you can use to create custom docker images containers all the KERN packages combined with your own scripts.
The Dockerfile below is all you need to setup a docker container for any of the packages in kern:
FROM kernsuite/base:dev RUN docker-apt-install aoflagger
The kernsuite docker image is a clean ubuntu system with the kern suite repository enabled. It also contains an up-to-date pip so you can directly install Python libraries. The docker-apt-install command is just a wrapper script that updates the apt cache before installing the package followed by a removal of the apt cache. This is the best way to prevent adding of clutter to your docker image and the image size to explode.
You can also have a look at the Dockerfile.
KERN has a presuccessor named the radio-astro launchpad PPA. This PPA is not updated anymore and renamed to KERN-0.
Ubuntu is one of the mostly used Linux distributions in (radio) astronomy, or at least in Europe and Africa. For now we base KERN on the latest Ubuntu LTS with a delay of 6 months up to a year. For KERN-0 this was Ubuntu 14.04, following releases are based on Ubuntu 16.04. KERN-4 is based on 18.04
For now this is just too much work, so no. The recommended way to use KERN when you are not running a supported platform is with Docker, Singularity or in a virtualmachine. We made Vagrant files for you already.
Surprisingly KERN works quite well on Windows 10. You need Bash on Ubuntu On Windows. On OSX we recommend to use Docker.

Not recommended and unsupported, but we are not stopping you.
Don't panic! They are actually existing but in a different repository. You can enable the debug repository by editing /etc/apt/sources.list.d/kernsuite-ubuntu-kern-4-bionic.list and copying the line starting with deb and appending /debug to it. It should look something like this:
There is no fixed release date, but we intent to release a KERN release every 6 months.
