Hello, 

I am trying to build the Voxl portal and the first step is to launch the voxl cross docker. I have installed the voxl docker, cross docker, and docker engine all on my ubuntu machine. (18.04.5 LTS)

When running "sudo voxl-docker -i voxl-cross", I get the following error:

"Unable to find image 'voxl-cross:latest' locally
docker: Error response from daemon: pull access denied for voxl-cross, repository does not exist or may require 'docker login': denied: requested access to the resource is denied."

I am not sure why it is says the repository doesn't exist because I installed the voxl-cross image from the downloads page (https://downloads.modalai.com/) and it is in the voxl-docker folder.

am I doing something wrong?

thanks,
Eli

I figured it out!

I was following the gitlab page to install the cross docker, which is incorrect when using the prebuilt image from the modalai website. (https://gitlab.com/voxl-public/support/voxl-docker)

following this documentation actually works: https://docs.modalai.com/voxl-cross/
