Data sent to CanonicalΒΆ

The Livepatch Client sends periodic requests to servers hosted by Canonical to check for the availability of new patches. These requests are sent at a configurable interval (every 60 minutes by default) and include the following information:

  • System architecture

  • CPU model

  • Kernel version

  • Boot time and uptime

  • Unique machine identifier, derived from /etc/machine-id

  • Version of the currently applied live kernel patch, if any

  • Current state of the system (whether a live kernel patch has been applied)

  • Time of the last server request

  • Livepatch Client version
