App Control: Upgrade failure on B9Notifier dependency for Linux agent

Products

• Carbon Black App Control (formerly Cb Protection)

Issue/Introduction

Symptoms include:

1. When trying to upgrade the Linux App Control agent using the relevant .bsx file, the -n switch to disable the b9Notifier from being installed, is not being honored 
2. Upgrade fails on a file dependency for the b9Notifier
3. Using the -n switch is not working 

Environment

• App Control Linux Agent: All Supported Versions
• Linux OS: All Supported Versions

Cause

The -n switch is not compatible with the .bsx file during upgrade

Resolution

The upgrade .bsx file can be modified via the steps below:

1. Open the .bsx file you are going to use to upgrade the Linux agent in a text editor (nano, vi, vim, etc.)
2. In the file, look for a line that says "sh ./b9install.sh ${UninstallScriptOptions} -x "$TMPDIR"
3. The -n switch is ONLY compatible with the b9install.sh script, so the above line will need to be modified like:
4. "sh ./b9install.sh ${UninstallScriptOptions} -n -x "$TMPDIR" (minus quote marks)
5. Run the .bsx file again and the b9notifier will be skipped for install
