how to fix container runtime is not running

"Container runtime is not running" usually means that there is an issue with the container runtime or service. Here are some steps you can try to fix this issue:

1. Check if the container runtime service is running. You can do this by running the following command:

   sudo systemctl status docker

If the service is not running, start it using the following command:

   sudo systemctl start docker

2. Check if the container runtime is installed. You can do this by running the following command:

   docker version

If the command returns an error, it means that the container runtime is not installed. Install the container runtime using the appropriate installation instructions for your operating system.

3. Check if there are any issues with the container runtime configuration. You can do this by checking the container runtime configuration file. For example, for Docker, you can check the `/etc/docker/daemon.json` file.

If there are any issues with the configuration, fix them and restart the container runtime service.

4. If none of the above steps work, try restarting your system and then check if the container runtime service is running. If it is not running, start it using the command mentioned in step 1.

I hope this helps! Let me know if you have any further questions.
