MDATP apt-get install fails Ubuntu 21.04

Brass Contributor

We are trying to install and test MDATP on Ubuntu 21.04. The installation fails at the install. If I swap with any other package the install starts fine. After digging into the files it looks like maybe MDATP is missing from the Contents-amd64.gz at


Note the size difference from 20.10 to 21.04

Also, the 21.04 contents contains zero references to MDATP or the opt folder


$ sudo apt-get install mdatp

If any one else runs into this, according to a MS team member this hasn't been released for 21.04 since it not LTS, and very new. That would explain the package not being available.
I did face the same issue and I got the same reply as well. MDATP is supported for LTS versions only.

I have the same issue, my machine info as follow:

Static hostname: ubuntu-linux-20-04-desktop
Icon name: computer-vm
Chassis: vm
Virtualization: parallels
Operating System: Ubuntu 20.04.2 LTS
