Ubuntu Landscape allows you to keep systems updated when deployed in large clusters.
If you clone a machine and look in its logs you might find an error message similar to the ones below.
Error message:
during refresh: cannot check: cannot send status to server: bad server status 403 (URL: https://livepatch.canonical.com/api/machine/dfb8755a82202da0678c99065c9501ab): {"error": "Invalid Machine Token"}
You may also see this warning in the motd.
* Canonical Livepatch is enabled. - Livepatch server check failed. Please see /var/log/syslog for more information.
The solution is to remove, reinstall landscape and register the node again with your license key.
apt remove landscape-common apt install landscape-common
It’s not clear if this is a bug or intended behavior for Landscape.
For large deploymens this could be problematic.
