What is the Pro upgrade daemon?#

Ubuntu Pro Client sets up a daemon on supported platforms (currently GCP only) to detect if an Ubuntu Pro license has been purchased for the machine. If a Pro license is detected, then the machine is automatically attached.

If you are not interested in Ubuntu Pro services and don’t want your machine to be automatically attached to your subscription, you can safely stop and disable the daemon using systemctl:

sudo systemctl stop ubuntu-advantage.service
sudo systemctl disable ubuntu-advantage.service
