ERROR: Unable to run Plesk Installer. Possible reasons:
1) You are trying to run Plesk Installer on an unsupported OS. Your OS is Debian-7.0. The list of supported OS is at https://docs.plesk.com/release-notes/current/software-requirements/
2) Temporary network problem. Check your connection to autoinstall.plesk.com, contact your provider or open a support ticket.

Debian, Ubuntu, CentOS, all are said to be supported, but I can not install Plesk on any of these. WIll you please help?
