after i go ahead with the installation this happens:
Command which failed was: " sed -i 's/YoutubeDLPath = \"\"/YoutubeDLPath = \"\/usr\/local\/bin\/youtube-dl\"/g' $LOCATION/config.ini". Please try to execute it manually and attach the output to the bug report in the forum thread.
If it still doesn't work report this to the author at https://forum.sinusbot.com/threads/sinusbot-installer-script.1200/ only. Not a PN or a bad review, cause this is an error of your system not of the installer script. Line 935.
