I attempt to start Ostinato 1.2 for Linux and the Drone core dumps

[Edwin Mallette]

New install running on Ubuntu 22.10.

systemctl status drone

I guess I resolved this.  I was attempting to apply rights as directed so I didn't have to use sudo to successfully start Ostinato.  I did two things - one I created a drone.ini file but that by itself wasn't the correction as it was still crashing after that.  Second is that I I started Ostinato as root.  I had previously applied the rights as specified in one of the tech notes...

sudo chown root /bin/drone
sudo chmod u+s /bin/drone

But I suppose additional rights are needed -- possibly to drone.ini.

Hi Ed,

The crash is unexpected. Can you try starting the drone directly with the '-d' flag?

drone -d

This will emit debug logs on the console. Save 'em in a file and attach here so that I can take a look.

You should not need to run Ostinato as root, please use the setcap method from https://ostinato.org/docs/faq#q-i-dont-like-running-ostinatodrone-as-root-is-there-an-alternative

Let me know if that works.

Thank you for this.  I attempted do follow the faq previously and I guess I missed a step, so thanks for pointing that out.

As far as the crash is concerned, I rebooted the host that was running Ostinato and after that, the drone hasn't crashed once and I've run it maybe a dozen times.  If it happens again, I will issue the debug commands and capture them.

Thanks!

Ed

Thanks for the confirmation, Ed!
