Automation Engine on Linux

Has anyone got the Automation Engine working on the Linux Platform Server recently? I have followed all steps for setup of the Automation Engine found in the HCL docs at

I have verified prerequisites and followed all install instructions. When I try to run a plan, I see a message that says “Error: Unable to find the public key to encrypt data”.

I see that there is a wizard to configure the automation key for BigFix on Windows, but I see no fixlet to do this for Linux, nor do I find a reference to needing to do this in the setup instructions or prereqs. Maybe I missed something?
