Question: On a local Debian Installation, halyard daemon is not starting. Showing the following exception: "Is your daemon running?"

Answer: This might occur if the Halyard was not shutdown properly before shutting down the server

1. First try to restart halyard "sudo service halyard restart" and, if it still doesn't come up...

2. Check for the status of the halyard "sudo service halyard status". 

         If it shows inactive then try to start again "sudo service halyard restart"

3. In case if the service doesn't respond with above #1 & #2, try "sudo update-halyard"
