(Question) Errors when setting usbmuxd as a service with systemd, but executes normally via terminal.

[autor3iv]

I'm trying to set up usbmuxd to run as a service, however I keep running into the following error :

    Dec  3 10:29:19 asci-kubu-NUC7i3BNH systemd[1]: asci-usbmuxd.service: Main process exited, code=exited, status=1/FAILURE
Dec  3 10:29:19 asci-kubu-NUC7i3BNH systemd[1]: asci-usbmuxd.service: Failed with result 'exit-code'.
Dec  3 10:29:24 asci-kubu-NUC7i3BNH systemd[1]: asci-usbmuxd.service: Service hold-off time over, scheduling restart.
Dec  3 10:29:24 asci-kubu-NUC7i3BNH systemd[1]: asci-usbmuxd.service: Scheduled restart job, restart counter is at 46078.
Dec  3 10:29:24 asci-kubu-NUC7i3BNH systemd[1]: Stopped usbmuxd service.
Dec  3 10:29:24 asci-kubu-NUC7i3BNH systemd[1]: Started  usbmuxd service.
Dec  3 10:29:24 asci-kubu-NUC7i3BNH usbmuxd[29950]: [0] Could not open lockfile

When I run it manually like so :

sudo usbmuxd -v --user usbmux --foreground

Everything is fine.

Here is my systemd .service file. I've read through the manual however I'm positive that I may have not set the correct capacities. I've verified the permissions/groups for usbmux user, usbmux is part of plugdev and sudo.

[Unit]
Description=usbmuxd service

[Service]

# Output to syslog

#Change this to find app logs in /var/log/syslog

Any help would be appreciated, I've dug around as best I could trying to find a solution. Thanks!

User usbmux cannot access the lockfile, remove these lines:

User=usbmux
Group=sudo

This file is used as a template to create the usbmuxd.service. After you build, you should have the final usbmuxd.service file that you need.

You can copy the generated file to /lib/systemd/system/usbmuxd.service and restart the service:

sudo systemctl restart usbmuxd

In your version probably the --systemd flag was missing.
