Default-Start contains no runlevels, aborting

Question

I'm trying to check if this solution would help me with auto restarting after shutdown.

But command sudo systemctl enable haltusbpower.service is followed by error:

Synchronizing state of haltusbpower.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable haltusbpower update-rc.d: error: haltusbpower Default-Start contains no runlevels, aborting.

My /usr/lib/systemd/system/haltusbpower.service file:

[Unit]
Description=haltusbpower
Before=shutdown.target
DefaultDependencies=no

[Service]
ExecStart=/usr/local/bin/haltusbpower.sh
Type=oneshot
RemainAfterExit=yes

[Install]
WantedBy=shutdown.target

My /usr/local/bin/haltusbpower.sh script:

#!/bin/bash
for i in /sys/bus/usb/devices/*/power/control;
        do echo on > $i
done

It has execute option:

karol@karol:~$ ls -l /usr/local/bin/haltusbpower.sh
-rwxr-xr-x 1 root root 88 kwi 27 13:03 /usr/local/bin/haltusbpow

Why enabling haltusbpower doesn't work? And what followed error means? I don't understand where to look for errors.

Solution 1

At the top of your /usr/local/bin/haltusbpower.sh script add something like this:

#!/bin/bash
### BEGIN INIT INFO
# Provides:          haltusbpower
# Required-Start:    $all
# Required-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:
# Short-Description: Halts USB power...
### END INIT INFO

Solution 2

I had the same error message but it included a message about missing LSB tags and overrides.

I looked in htop and had multiple processes tailing the log from when I tested the service using /usr/local/bin/./MyService.sh start and /usr/local/bin/./MyService.sh stop. Once I killed these processes it was successful.

The start and stop test command was taken from http://www.jcgonzalez.com/ubuntu-16-java-service-wrapper-example

I found my answer in this forum thread Long story short I had my old System V (service) file in my /etc/init.d directory so the system was trying to resolve the legacy code as well

Can you add some explanation to this?

"haltusbpower" should be replace with your service name.
