Our squid proxy server can no longer access the internet in AWS. When trying to apt-get update:

root@ip-172-31-76-59:/home/ubuntu# apt-get update
Err:1 http://security.ubuntu.com/ubuntu bionic-security InRelease
 Temporary failure resolving 'security.ubuntu.com'

Trying to access cache logs but spits back "permission denied" even as root. May have to do with apparmor installed? Any assistance would be appreciated.

The AppArmor installed prevented access to the DNS settings and unable to validate the settings. It was easy enough to start from scratch and rebuild a new server to resolve this issue.
