Cannot start Calibre-server (code=exited, status=203/EXEC)

[don_caviare]

Hi all,
I've been following this tutorial, in the hope that I can set up my Calibre server to start up automatically at boot on my Raspberry Pi (running Raspbian Stretch). X libraries are installed.

It seems like the server fails to start...

● calibre-server.service - calibre content server
   Loaded: loaded (/etc/systemd/system/calibre-server.service; disabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Fri 2020-03-27 19:48:02 GMT; 6min ago
 Main PID: 29349 (code=exited, status=203/EXEC)

Mar 27 19:48:02 raspberrypi systemd[1]: Started calibre content server.
Mar 27 19:48:02 raspberrypi systemd[1]: calibre-server.service: Main process exited, code=exited, status=203/EXEC
Mar 27 19:48:02 raspberrypi systemd[1]: calibre-server.service: Unit entered failed state.
Mar 27 19:48:02 raspberrypi systemd[1]: calibre-server.service: Failed with result 'exit-code'.

This is my super-simple config:

[Unit]
Description=calibre content server
After=network.target

[Service]
Type=simple
User=pi
Group=pi
ExecStart=/opt/calibre/calibre-server "/media/pi/yarblup/booklibnew"

[Install]
WantedBy=multi-user.target

Any idea what the problem might be? Is the server failing to locate the library?
Things work fine when just using calibre-server in terminal.

All help appreciated!

That error means /opt/calibre/calibre-server doesn't exist or the user pi does not have permission to read/execute it.

Brilliant! Thanks Kovid. I kept double-checking my library path, and forgot to check my application path... *facepalm*
Turns out calibre-server was installed in /usr/bin/.

Eternal gratitude to you (and others) for developing this splendid software.
