MDE Linux: machine_guid: "unavailable"

HI,

on my MDE installation the machine_guid is "unavailable" and this seems to cause some few disfunctionalities.

I have hidden/cutoff some information but so far it looks good. 

Do you have an idea what to check? a reinstall did not work but I did no reboot. I will now do a uninstall - reboot - install... but I don't think thios solves it!?

Any help or idea to check/debug here would be nice. Thank you.
