  • Why did you tag 14.04? Ubuntu 14.04 LTS is EOL & thus off-topic, Ubuntu 14.04 ESM is off-topic as all ESM releases are being supported only through Ubuntu Advantage offered by Canonical. https://askubuntu.com/help/on-topic – guiverc Nov 24 '19 at 11:54

I guess you want to use change the owner of the folder. Use chown ("change owner") instead of usermod:

  sudo chown -R root.xamppusers /opt/lampp/htdocs
