Incorrect DNS Record for packages.ros.org Preventing ROS Installation

Subject: Incorrect DNS Record for packages.ros.org Preventing ROS Installation

Dear ROS Maintainers,

I am writing to report a critical issue with the DNS record for packages.ros.org that is preventing the installation of ROS packages on Ubuntu 20.04 (focal) system.

My name is John A. (Tony) Dutcher.

When attempting to access packages.ros.org for ROS package installation, my system is being redirected to ftp.osuosl.org (Oregon State University Open Source Lab) due to an incorrect CNAME record in the DNS. This redirection leads to the retrieval of the OSUOSL server's SSL certificate instead of the correct certificate for packages.ros.org, resulting in SSL certificate verification failures.

Specifically, the dig packages.ros.org command returns:

packages.ros.org. 600 IN CNAME ftp.osuosl.org.
ftp.osuosl.org. 599 IN A 64.50.236.52
ftp.osuosl.org. 599 IN A 64.50.233.100
ftp.osuosl.org. 599 IN A 140.211.166.134
This incorrect DNS configuration causes:

SSL certificate mismatch errors during openssl s_client connections.
GPG key verification failures during sudo apt update.
The inability to install ROS packages (e.g., ros-noetic-desktop-full).
I have verified that this issue is not specific to my system's configuration by testing from a new user account on the same system. I have also verified that the issue is not related to my local network, or /etc/hosts file.

I kindly request that you investigate and correct the DNS record for packages.ros.org as soon as possible.

Thank you for your time and attention to this matter.

Sincerely,

John A. (Tony) Dutcher
