Hi Guys,

Just made a fresh install of a Jdownloader 2 on my Ubuntu Server (16.04) and it won't launch because of those errors:

Any help please :D

ownership issue?

Can not write to /opt/jd2/

fix the chown/chmod permissions to match with the user that runs JDownloader

ok will do that.
THanks mate

sudo chown -R user:group /opt/jd2/
remplace user:group with your own user

Thanks a lot mate, that was only that :D
