Disable APT news using the Ubuntu Pro command line utility.

$ sudo pro config set apt_news=false

Alternatively, alter configuration file and reload it.

$ cat /etc/ubuntu-advantage/uaclient.conf 
# Ubuntu Pro client config file.
# If you modify this file, run "pro refresh config" to ensure changes are
# picked up by Ubuntu Pro client.

Ubuntu Pro is free on up to 5 machines for everyone, so you can always try it out and I strongly recommend to do so.
