A packages named ubuntu-advantage-tools scrolled into my view while updating Ubuntu.
After reading the description
> It is a command line interface providing a single point of entry for enabling, disabling and maintaining Ubuntu Advantage support services on a single machine or cloud instance. It interacts with a backend https://contracts.canonical.com
with GETs and POSTs over https to extract configuration directives to add or remove apt repos, install deb packages and/or snaps (in the case of livepatch).
I removed the package
sudo apt-get remove ubuntu-advantage-tools
