Cb Response: Linux sensor installer script fails when called from remote directory

Products

• Carbon Black EDR (formerly Cb Response)

Issue/Introduction

When manually installing the Cb Response Linux Sensor from a remote directory, the install script fails.
Error:

############################################################################
## Installing cbsensor from /root/downloads/sensor_builds/6.1.8_Linux_sensor/__Download
## Error: Installation Package is not present

 

Environment

• Cb Response Linux Sensor: 6.1.7 - 6.1.8
• Linux: All Supported Versions

Cause

The installer script is not looking for the RPM files in the proper location. This is a known issue under investigation. 

Resolution

1. From the CLI, change to the same directory as the installer script.
2. Launch the upgrade script from within the current directory:

# ./cb-installer-script.sh

Additional Information

• This issue is resolved in Cb Response Linux Sensor 6.1.9 and later.
• An alternative workaround is to not upgrade the Linux endpoint manually but to use the Cb Response web interface to automatically upgrade it.
• This may occur as an interop issue with IBM BigFix integrations.
