# This service runs on GCP and Azure to enable auto-attaching to Ubuntu Pro
# services when an Ubuntu Pro license is added to a machine.
# It also serves as the retry service if an auto-attach fails and will
# retry for up to one month after the failed attempt.
# If you are uninterested in Ubuntu Pro services, then you can safely
# stop and disable this service:
# sudo systemctl stop ubuntu-advantage.service
# sudo systemctl disable ubuntu-advantage.service
