All in one Ubuntu install on 16.04 fails with

Hello @jess,
I have started fresh with a new Xen VM and fresh install of Ubuntu 16.04.7. I’ve setup all of the pre-requisites and proceeded with the Kaltura installation and it has once again failed as follows:

Hit:1 xenial InRelease
Hit:2 xenial InRelease
Get:3 xenial-updates InRelease [109 kB]
Hit:4 stable InRelease
Get:5 xenial-backports InRelease [107 kB]
Hit:6 xenial InRelease
Get:7 xenial-security InRelease [109 kB]
Get:8 propus InRelease [1,426 B]
Ign:8 propus InRelease
Fetched 327 kB in 1s (208 kB/s)
Reading package lists… Done
W: GPG error: propus InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY DE7AA37623C65ECB
W: The repository ‘ propus InRelease’ is not signed.
N: Data from such a repository can’t be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.

I noticed that the install is pointing to propus, but the documentation lists:
echo “deb [arch=amd64] naos main” > /etc/apt/sources.list.d/kaltura.list
as the list. I am including the commands from my documentation of this install in the order I run them in the hopes of clarifying where I am going wrong. As always, your assistance is appreciated.
