We released a quick fix to our runtime preview on Linux, version 18.104.22.168. With the latest release of Docker on Linux, the "docker daemon" command was removed which prevented the Service Fabric runtime from starting the daemon. The 22.214.171.124 update to the Service Fabric runtime uses the recommended "dockerd" command instead for starting the Docker daemon.
To update from a current version of the runtime on your developer environment, perform the following steps:
sudo apt-get update
sudo apt-get install servicefabric
If you are installing for the first time, please follow the instructions in http://aka.ms/sflinux.
