Deprecation of appliance versions

Since release 7.28, sensor versions before 720 are no longer compatible with Lastline backend.

Distribution Upgrade

Sensor 1055, which is being made available as part of this release, does not support Ubuntu Trusty as the underlying operating system distribution. Before upgrading, you will need to upgrade your operating system distribution to Ubuntu Xenial.

Users can check the distribution in use by an appliance in the Appliance Status view of the portal. The "Base Distribution" listed should be "xenial". If it is "trusty", the appliance distribution should be upgraded. A distribution upgrade can be performed by ensuring the sensor is on version 1051 and following these instructions for help with the upgrade process. This update is not done automatically to prevent unexpected downtime.

For complete information regarding the upgrade process please refer to the Lastline Support Knowledge Base.
