I have a server based on an H8DG6-F MB. I have tried to install SuperDoctor5 several times in Ubuntu 16.10 server (with Ubuntu-desktop).
Each time I have wiped the system clean and reinstalled the operating system. However, I'm getting the message. Please uninstall any previous SD5 installation.
Please try the following command to over write previously installed SD5.
/SuperDoctor5Installer_5.3.0_build.663_linux_x64_20151217141907.bin -i silent -f installer_agent.properties
