Ubuntu 16.04 droplet can't shut down, any ideas on how to find out why?
I’ve created a droplet with Ubuntu 16.04, set up the basic security/firewall settings, and apt installed a few things (java, tomcat8, apache2, mysql).
Everything is working fine when the server is running, but when I sudo poweroff it seems to get stuck. After running poweroff it is inaccessible but still shows up as running in the droplet web UI, and snapshots do not work.
In order to get it to fully power off, I need to click the Power > Power Off button in the web UI.
Does anyone know of a way to troubleshoot this, or logs to check to find out why it’s happening? I looked in /var/log/* but didn’t notice anything related to shutdown problems. I also tried systemctl stopping the services I installed before poweroff, but this didn’t help either.
Thanks for any ideas.
