Hello there !

I have an issue with JDownloader on Raspbian Jessie (Raspberry Pi 2B+), I hope you could help me on this.

I want JDownloader to start on my Raspberry Pi startup. Raspbian Jessie uses systemd for that, so here is my script :

### startjdownloader.service ###

[Unit]
Description=Start JDownloader
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/java -jar /home/pi/jdownloader/JDownloader.jar
User=pi

[Install]
WantedBy=multi-user.target

But it only seems to be stuck in an update loop :

$ sudo systemctl status -l startjdownloader.service 
● startjdownloader.service - Start JDownloader
   Loaded: loaded (/etc/systemd/system/startjdownloader.service; enabled)
   Active: active (running) since jeu 2017-07-27 15:28:45 CEST; 8h ago

   CGroup: /system.slice/startjdownloader.service
           └─2396 /usr/bin/java -jar /home/pi/jdownloader/JDownloader.jar

I have translated some of the logs above so it is all english, they might slightly differs from the original english ones.

Any idea where it could come from ?

Thanks in advance !

Your systemd script is wrong and will break installation/update because JDownloader restarts itself
See
github.com/OpenMediaVault-Plugin-Developers/openmediavault-jdownloader/blob/master/debian/jdownloader.service

Type=oneshot
UMask=000
RemainAfterExit=yes

Working indeed, thanks a lot !
