2 years ago This is not a kappanhang issue. Pulseaudio is required for kappanhang, you have to make sure it is installed and running before starting kappanhang. Try adding After=sound.target to the Unit section in your systemd service file.

2 years ago I will try that but keep in mind that before starting the service I tested it from the command line. I started the service after the whole system booted up

2 years ago Your service file starts kappanhang probably as user root, which does not have a running pulseaudio instance, and it also can't access the running PA instance of your user.

2 years ago You can read from the service file that the service is running as the user 'pi'. I also see it running as 'pi' by running ps aux
pi 14584 0.5 0.2 891344 11788 ? Ssl 15:39 0:01 /home/pi/go/bin/kappanhang

2 years ago Then something else causes the PA instance inaccessibility, for ex. systemd starts kappanhang without access to the current user's dbus session.

2 years ago Hi, Try this:
ExecStart=/bin/bash -c '/home/pi/go/bin/kappanhang'
This will help ensure the environment is set correctly for the pi user. This might be important in bringing in some environment variables that PA might use.

I've created this simple service file:
[Unit] Description=kappanhang After=syslog.target network.target [Service] Type=simple ExecStart=/home/pi/go/bin/kappanhang ExecReload=/bin/kill -HUP $MAINPID RestartSec=60 Restart=always User=pi [Install] WantedBy=multi-user.target
when I run the service it starts but then it crashes with a "panic: runtime error: invalid memory address or nil pointer dereference" error.

2 years ago Hi @VK2KTJ ,
that didn't work but thanks to @nonoo 's tip I was able to run it as a user's service.
All I had to do is change the service file kappanhang.service to this:
[Unit]
Description=kappanhang
DefaultDependencies=no
After=local-fs.target time-sync.target
[Service]
Type=simple
ExecStart=/home/pi/go/bin/kappanhang
ExecReload=/bin/kill -HUP $MAINPID
RestartSec=60
[Install]
WantedBy=default.targetcopy it into /home/pi/.config/systemd/user/ and the run

2 years ago That's good to know. I might revisit a couple of my own services to see if this makes more sense for those too. Thank you.

Hi, I tried to configure a systemd service for kappanhang so that it can connect and run in the background on my raspberry pi. kappanhang runs fine when launched from the terminal
I've created this simple service file:
when I run the service it starts but then it crashes with a "panic: runtime error: invalid memory address or nil pointer dereference" error.
