Current Behavior

Attemped to setup a fresh install of Headascale. Followed the steps on "https://headscale.net/stable/setup/install/official/". After updating 'config.yaml', start of service and received the following error:
Process: 20956 ExecStart=/usr/bin/headscale serve (code=exited, status=1/FAILURE)
Main PID: 20956 (code=exited, status=1/FAILURE)
CPU: 125ms

Install should run smoothly

Environment

- Headscale version: 0.25.1

  • Headscale runs in a container

Debug information

Should be a simple install. It appears something is missing in either the procedure or install script.

Spacing and indentation is important in a yaml configuration file. Please ensure to preserve the indentation and probably check the configuration file with yamllint or an online yaml validator. The configuration you posted is invalid because all indentation is lost.

Thanks, that's a good point. yamllint didn't find anything, but jasonformatter did. A bad indent on the listen_addr line was the culprit. Sorry to have bothered everyone.
