Ubuntu Unix login_duo permissions error


#1

Tried installing on Ubuntu 16.04 server 64 bit.
I’m getting an error on the login_duo.conf file that it must only allow read access to the user who is signing in.
I installed by adding package source of: deb http://pkg.duosecurity.com/Ubuntu XENIAL main
even though xenial wasn’t mentioned.
I tried several permissions on the conf file with no luck.
