MyJDownloader Account Required

You must have a MyJDownloader account to use JDownloader on QuickBox. The account credentials are required during installation to link your server instance for remote management.

Installation

MyJDownloader account required first

Create a free MyJDownloader account at my.jdownloader.org before installing — its email and password are entered at install time to link your server for remote management.

Install from the Dashboard

Open App Dashboard → Package Management (/dashboard?mode=packages), find JDownloader in the catalog (browse Download Clients or search), and click Install. The install dialog collects three fields:

Download Path — where finished files land (defaults to /home/username/Downloads).
MyJDownloader Email — the account email used to link the instance.
MyJDownloader Password — the matching account password.

The dashboard streams the install log live and JDownloader appears in your Application Control panel when it finishes. Reinstall, Update, and Remove are available from the same panel.

What you see and can manage is gated by your account: admins manage any user’s apps; regular users manage their own. For the full package flow see App Management.

Install from the CLI (automation)

The CLI runs the same install and is suited to automation and scripting. It takes the same email, password, and download-path inputs:


qb install jdownloader -u username -e 'your@email.com' -p 'yourpassword'

Command	Description
`qb install jdownloader -u user -e 'email' -p 'pass'`	Install JDownloader with MyJDownloader credentials
`qb reinstall jdownloader -u user -e 'email' -p 'pass'`	Reinstall while preserving configuration
`qb remove jdownloader -u username`	Remove JDownloader and clean up files
`qb update jdownloader -u username`	Update JDownloader to the latest version

CLI Options

-e, --emailRequired

Access & Remote Management

JDownloader on QuickBox runs headless (no GUI). Manage your downloads remotely via:

Web Interface: my.jdownloader.org
Mobile Apps: JDownloader apps for iOS and Android
Browser Extensions: Click-to-download extensions for Chrome/Firefox

Your QuickBox JDownloader instance will appear in MyJDownloader as username@hostname.

Browser Extensions

Install the MyJDownloader browser extension to send download links directly to your QuickBox server with a single click.

Services

JDownloader uses a templated systemd unit (jdownloader@.service) running as a Java headless process:


# Check status
systemctl status jdownloader@username
 
# View logs
journalctl -u jdownloader@username -f
 
# Restart service
systemctl restart jdownloader@username

Best Practices

Do

Use a dedicated MyJDownloader account for your server.
Set a custom downloads directory with -D if needed.
Monitor disk space—JDownloader can fill storage quickly.

Don't

Do not share your MyJDownloader credentials publicly.
Do not manually edit systemd files—use qb commands.
