I think the Neurodebian group only maintains backports in their own neurodebian repositories. Singularity's development is moving rather quickly and the freeze kind of made the official Debian backports of singularity uselessly outdated for those several months. Now, of course, we can use jessie-backports-sloppy and stretch-backports, but singularity there is still outdated at the moment. > I have also seen > Roland in the changelog. Many thanks!

Our group at the US NIH HPC has also a guide and tutorial for our users: https://hpc.nih.gov/apps/singularity.html https://github.com/NIH-HPC/Singularity-Tutorial My old colleague who wrote those actually ended up moving on to a job as a singularity developer. I think a very successful Debian example would make use of snapshot.debian.org as a mirror in the definition file in order to be able to regenerate exactly the same container at any time. regards Afif -- Afif Elghraoui | عفيف الغراوي http://afif.ghraoui.name
Getting user-space containers with Singularity - works
Hello, Many (most) HPC administrators very much detest the idea to grant any sort of root privileges to their users. This consequently rules out the installation of our Debian packages and also the employment of Docker images for the execution of binaries. Ouch! After all, with this perpetual avalanche of biological data we are often dependent of some sort of shared infrastructure for storage and/or computation. Also, for consistency within long-running projects, one cannot just go and update Debian packages because of a new project starting. Every project comes with its own set of versioned tools and data. These are prime use cases for containers - if they would just work as regular users. To the rescue comes Singularity. It does what you would want to do with Docker, without extra privileges: * deliver a set of tools and/or data readily configured for the task * become Linux-distribution agnostic * continue working with Docker images of yours or your collaborators Our pals from neuro.debian.net are already actively using this technology and kindly nurture backports.d.o with it. I have also seen Roland in the changelog. Many thanks! With feedback from Yaroslav I created a quick introduction to get you started at https://wiki.debian.org/singularity. It is quite an eye opener. Enjoy! Best, Steffen
