=== Livepatch ===
  This machine ID is already enabled with a different key or is non-unique.
Or
  error executing enable: cannot enable machine: bad temporary server status 500
Likely you installed your VM with a template and the machine ID is not unique.\\
But you can easy fix that.\\
  rm -f /etc/machine-id
  dbus-uuidgen --ensure=/etc/machine-id
  rm /var/lib/dbus/machine-id
  dbus-uuidgen --ensure
  
You need to reboot afterwards.\\
**Warning: Some people say it might fuck up things.**\\
So far it worked fine even on running LXD nodes (no clusters tested).
