Install Java and get JDownloader with the following commands.

sudo apt install openjdk-8-jre-headless
wget http://installer.jdownloader.org/JDownloader.jar

After that move JDownloader.jar and change the owner to the user (e.g. media) under which JDownloader should be executed.

sudo mkdir /opt/jdownloader
sudo mv jdownloader.jar /opt/jdownloader
sudo chown media:media /opt/jdownloader

Now we are ready to install JDownloader. Execute this command several times until you get asked for your My JDownloader login credentials on the console.

java -jar /opt/jdownloader/JDownloader.jar -norestart

Then create a new systemd unit under /etc/systemd/system/jdownloader.service and paste this script.

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

[Service]
Environment=JD_HOME=/opt/jdownloader
Type=oneshot
ExecStart=/usr/bin/java -Djava.awt.headless=true -jar /opt/jdownloader/JDownloader.jar
RemainAfterExit=yes
User=media # Should be owner of /opt/jdownloader
Group=media # Should be owner of /opt/jdownloader

[Install]
WantedBy=multi-user.target

To enable JDownloader on startup run this command.

sudo systemctl enable jdownloader.service

After a reboot you can access your server under https://my.jdownloader.org

Enjoy!

First of all thanks @wuethrich for the guide.

I followed it step by step and all seemed to be fine until i rebooted.

When booting it return me the message: FAILED: failed to start jdownloader service

I've tried

systemctl status jdownloader.service

and it returns me the following messages:

jdownloader.service - JDownloader Service
   Loaded: loaded (/etc/systemd/system/jdownloader.service; enabled; vendor preset: enabled)

Help!

SOLVED!

[Jiaz]

Would be nice if you can share how you solved it ?

There were formatting errors about the new systemd unit creation.

Here below the right code:

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

[Service]
Environment = /opt/jdownloader
Type = oneshot
ExecStart = /usr/bin/java -Djava.awt.headless=true -jar /opt/jdownloader/JDownloader.jar
RemainAfterExit = yes
User = media
Group = media

[Install]
WantedBy = multi-user.target

Hope this helps someone.

[Jiaz]

Thanks for the feedback!

@Jiaz

Thanks for this. It worked perfectly.
How can I start the JDownloader Interface once it has already beeing configured (to change login for example).

Solved!
(I used the web gui with advanced options to achieve my goals)

Thanks

[Jiaz]

Thanks for the feedback! Glad you could solve it by yourself!

Hi,
when starting via systemd I suddenly got this error during bootup:

/etc/systemd/system/jdownloader.service:6: Invalid environment assignment, ignoring: /opt/jdownloader

now journalctl -b brings this:

And now I can't connect via myjdownloader...

When I start it via SSH after killing the original thread it works...

And then is there a second issue:

downloaded and extracted files are 755, which I cannot cut&paste them via Windows as network drive... Can I change new files automatically to 766? Due to issues I connect via guest

Thank you very much!

Hi, I'm not sure if it's fit, but I'm running exactly this setup.
When I want to delete an extracted file, I cannot, due to file permission. my samba user is heimnetz. the owner of the new file is root:heimnetz with 755...

When I manually change to heimnetz:heimnetz it works. An idea how to change the owner permanently for new files to heimnetz:heimnetz?

[Jiaz]

@LeRob:
The *best* solution would be to start JDownloader as user *heimnetz*
sudo chown -R heimnetz:heimnetz /opt/jdownloader
sudo su -c "java -jar /opt/jdownloader/JDownloader.jar &" heimnetz

You can make use of *umask* to setup the umask of new created files/folders
eg
start.sh

#!/bin/bash
umask 000
cd /opt/jdownloader
java -jar JDownloader.jar >/dev/null 2>/dev/null &

sudo -c "start.sh" heimnetz

I enabled jdownloader.service and got this staus:

Jul 21 07:58:01 odhc1-02.local systemd[1]: jdownloader.service: Unit configuration has fatal error, unit will not be started.

I am wondering because of the message »jd # Should be owner of /application/JDownloader« it is not true und it is with the comment that was in my jdownloader.service file
Im am able to start »jd@odhc1-02:/application/JDownloader$ java -jar JDownloader.jar &« successful

I was wondering about the Java installation

root@odhc1-02:~# ll -h /usr/bin/ | grep java
lrwxrwxrwx  1 root root      22 Jul 20 13:57 java -> /etc/alternatives/java*

here my unit file »root@odhc1-02:~# nano /etc/systemd/system/jdownloader.service«

PS. I am using Ubuntu 22.02 on odroid hc1

[Broler]

Now I am able to create the deamon. The only notable differences i think exist are »After=network.target« and »PIDFile=/application/JDownloader/JDownloader.pid«.
Other differences are the omission of the group ID and type.

But this did not explain the errormessage because of »Invalid user/group name or numeric ID«.

Here the jdownloader.service file
