I’m in a similar boat, except I had to white-knuckle the install myself. White-knuckle, because I had to set up unique to my laptop certs beforehand to get on the corporate VPN. And if it disn’t work, I’d be off the VPN unable to connect (I work remote). Got it working, but, fun fact, my ubuntu laptop is running Microsoft Defender! (per requirements) I feel super protected.



Nah, there’s an official package/repo for ubuntu. It just requires an enterprise microsoft license.
