Carbon Black Cloud Sensor: Some Linux Endpoints Fail to Upgrade from Console

Products

• Carbon Black Cloud Endpoint Standard (formerly Cb Defense)

Issue/Introduction

• Some endpoints upgraded from the console never update
• Issuing the command again may or may not upgrade the sensor

Environment

• Carbon Black Cloud Console: All Versions
• Carbon Black Cloud Sensor: 2.11.0 and Below
• Linux: All Supported Versions

Cause

• At the time of upgrade, the upgrade request was dropped before it reached the sensor, possibly due to network issues. 
• The sensor will only receive the upgrade request once, if missed, it will never try again

Resolution

• Sensor version 2.11.1 will have a feature to receive new upgrade hints
• For older sensor versions, send another upgrade request from the console
