Hi @wouter the reason this is happening is recently docker depricated their api v1 version and are only using v2 api calls now. Meaning the original voxl is not able to pull down pre made docker images. The solution around this is to build the docker image on a parent computer, tar it up via docker save, then push that to the voxl and run a docker load -i on the tar file.
You can follow similar to what we do in voxl-docker-mavsdk:
