I'm trying to evoke a policy in the post install phase of a payload free package. I created the postinstall script in Composer and entered the line:



#!/bin/sh

## postinstall





jamf policy -event sierra-postinstall





exit 0      ## Success

exit 1      ## Failure


But when I install the package it doesn't run the policy that I have set up with trigger "sierra-postinstall". I can run the policy just fine via terminal.



Is this not possible with Composer? Or am I missing something?

Have you tried sudo jamf policy -event sierra-postinstall?



Another thought, could you trigger the policy via Execute Command from a Files and Processes payload in the policy that's installing the package rather than in the package itself?

Yeah no dice on adding SUDO. And while I could use the files and processes payload (maybe I will), ideally I would like to invoke it by a package. Thanks for your response!

@danshaw,



You may be running into an issue with the PATH environment variables not correctly identifying the location of the
jamf binary. Try running this:



#!/bin/sh

## postinstall



# This script runs a manual policy trigger to

# allow the policie(s) associated with that

# trigger to be executed.



trigger_name="$4"



CheckBinary (){



# Identify location of jamf binary.



jamf_binary=`/usr/bin/which jamf`



 if [[ "$jamf_binary" == "" ]] && [[ -e "/usr/sbin/jamf" ]] && [[ ! -e "/usr/local/bin/jamf" ]]; then

    jamf_binary="/usr/sbin/jamf"

 elif [[ "$jamf_binary" == "" ]] && [[ ! -e "/usr/sbin/jamf" ]] && [[ -e "/usr/local/bin/jamf" ]]; then

    jamf_binary="/usr/local/bin/jamf"

 elif [[ "$jamf_binary" == "" ]] && [[ -e "/usr/sbin/jamf" ]] && [[ -e "/usr/local/bin/jamf" ]]; then

    jamf_binary="/usr/local/bin/jamf"

 fi

}



# Run the CheckBinary function to identify the location

# of the jamf binary for the jamf_binary variable.



CheckBinary



$jamf_binary policy -event sierra-postinstall


I have a post on PATH environment variables and how they can affect Casper, available via the link below:

Removed..

Hey @rtrouton that did it! Thank you so much. It just needed to know where the JAMF binary was. Well done. And a quick thank you for your blog and all that you have contributed. It has helped me more than I can count.
