            As I'm working on this issue, I noticed the following.

            It's not showing any IP address for docker0.
            How to configure the IP address that will listen to docker daemon on voxl-core board?

              Hey @Alex123 were you able to resolve this? I'm having the same issue.

                Are you following the docs here?

                The voxl-docker command is for developing in a Docker on a PC, it should not be run on VOXL.

                The tutorial steps to run on target are:

                yocto:/# voxl-configure-docker-support.sh
yocto:/# docker images
yocto:/# docker run hello-world

                If you have run the PC scripts on VOXL, not really sure what would happen

                    Not really sure what state your system is in. This github issue shows it could be related to disk space or needs a reboot. Did you install other Dockers on the image? They are very large and maybe all of the space is consumed

                      Just looking at your script, I realized that modal has it's own docker services.. so perhaps this provides a little more info: I have created a few images from the kinetic image

                        I had a battery go pretty low and the system crashed while running mavros in docker last night, after reboot, docker deamon is not responding and I cannot see any images.

                          @kiprock I would reflash the system, setup your IP connection, configure Docker and just verify that it works as expected.

                            just looking at the logs, the docker deamon fails here:

                            level=fatal msg="Error starting daemon: Error initializing network controller: could not delete the default bridge network: network bridge has active endpoints"

                            Most forums suggest removing the docker network folder: rm -r /var/lib/docker/network

                            I did this but still having issues. Just curious if the modalAI setup stores docker files somewhere else?

                              @kiprock Everything is stored on /data. But again, I would reflash and start over just to verify Docker operation.

                                did the trick. Thanks for providing that missing piece of data!

                                  @kiprock Hi I have a exactly same issue.

                                  I flashed image and reset factory configuration on my VOXL, but, It has still issue.

                                  Did you resolve this problem?

                                  Thanks,

                                    @Eric-Katzfey if you cannot start docker images, you can try the command above to clear them. Good luck.

                                            @kiprock Thank you for this, that also solved the issue in my case.

                                            To be a little more cautious, I simply renamed the existing file, which forced the generation of a new one when running the configuration script voxl-configure-docker-support.sh:

                                            voxl:/data/network/files$ mv local-kv.db local-kv_DISABLED.db
