[Pofer_Wang]

hello everyone.

I have a problem.
I use ubuntu 20.4 desktop now.
I install Ignition 8.1.19 is normal,but I restart computer,ignition gateway can't run.

I need to enter

./ignition.sh start.

I try the command

sudo ./ignition.sh install

but it return "Must be root to perform this action."

[Bug-16797] Ignition Gateway Start on Linux on boot

This depends on your version of Ubuntu, but for most recent versions, you can use the systemctl command (as root). These are pretty simple commands: systemctl status ignition – Check the status systemctl start ignition – Start it now systemctl stop ignition – Stop it now systemctl enable ignition – Autostart on boot systemctl disable ignition – Remove the autostart symlinks Older versions of Ubuntu generally use init scripts.

I tried it!!

but it always return "unit Ignition not found."

Use sudo systemctl list-units to review the names in your system. v8.1 uses Ignition-Gateway as the service name, IIRC. (I always override that to plain ignition when I install.) Upper-case versus lower-case matters.

I can't find about any ignition message in units list
