I know Debian is not supported as a guest OS.
When I install the agent, I immediately get the message "Debian Not Supported".
I tried to find the OS check in the installation file, but I didn't find it.
Is there a chance to install an agent on Debian?
Not sure. Maybe yes. But it is not recommended to install Linux agent on an unsupported OS. Even you can bypass the OS check in the installer, some other (unexpected) issues may occur.
