Hi,

can i run jdownloader headless on a raspberry pi stretch? i want to controll the captchas with the android app as i can do when jdownload is running in gui mode. i found some howtos in the net but after running jdownloader the first time the temrinal output is completely different so them posted in the howto.

is it generaly possible to do this?

You can run JDownloader on nearly anything that runs Java
https://support.jdownloader.org/Know...bedded-devices

It's important to run JDownloader the first time with -norestart parameter so you can enter your MyJDownloader logins on console.

In case you encounter problems or need help, just ask again or contact us via support@jdownloader.org

wrong/invalid permissions. Your JDownloader is not allowed to write into /opt/jdownloader

sudo chown -R user:group /opt/jdownloader
use correct user and group values

looks like you've installed as root and now try to run as normal user
