Having Homebrew install issues on Mac OSX

[Cubert]

Your Mac never reports any data after enabling it. No brew version numbers get reported in agent EDFs for Package Manager version.

A common issue with the install of Homebrew through automation may cause Homebrew to fail install. Homebrew requires xcode commandline tools to be installed prior to Homebrew install.

We attempt to install the xcode tools for you but it is subject to failure and here is why. The tools require user acceptance during the install process which during an automated install is not there. There is a trick to backdoor this install by testing for an available update in the agents available update.

You can create a tmp file denoting that the commandline tools are on-demand and install is in progress. Then we have to see if the update to tool is available for this system, and here is where it fails. Not all systems will show an available update.

We use the following to capture the update if available:

Code: Select all

/usr/sbin/softwareupdate -l | grep -B 1 -E 'Command Line Tools' | awk -F'*' '/^ *\\*/ {print \$2}' | sed -e 's/^ *Label: //' -e 's/^ *// | sort -V | tail -n1 

This should return the title of the update available if one. If not then you will need to manually install xcode commandline tools by running the following sequence.
