Unable to get package on Ubuntu 18.04

[eddiemoto]

I’m trying to install DUO on an Ubuntu 18.04 server. I’ve followed the instructions but the package won’t install.

It is in the keyring as you can see below.

/etc/apt/trusted.gpg
--------------------

sub   elg4096 2013-09-05 [E] [expires: 2020-08-22]

However, when running the apt-get… I get the following…

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package duo-unix

What am I missing here?

Hi, did you create /etc/apt/sources.list.d/duosecurity.list and then add deb http://pkg.duosecurity.com/Ubuntu bionic main to it?
