Openshell gateway start command - Initializing environment Failure

[Porkroll7]

Hello, I'm a first time user. Trying to get OpenShell up and running, but can't seem to do so. Hopefully this is the right place to post a Help request.

`porkroll@porkroll:~/OpenShell$ openshell gateway start
✓ Checking Docker
✓ Downloading gateway
x Initializing environment x Gateway failed: openshell

Docker is not running

The Docker daemon is not running or not accessible. OpenShell requires a Docker-compatible container runtime to manage gateway clusters.

To fix:

1. Start your Docker runtime

2. Verify Docker is accessible

   docker info

3. If using a non-default Docker socket, set DOCKER_HOST:
   export DOCKER_HOST=unix:///var/run/docker.sock

4. Then retry: openshell gateway start

Error: × K8s namespace not ready
╰─▶ gateway container is not running while waiting for namespace 'openshell': container exited (status=EXITED, exit_code=2)

Also found some info here, and I got the logs, but don't know what it means...

Any help is appreciated!
