I use something @daz_wallace made that uses an EA to scope the update policy, but I can't find the blog.

Any using this python script to enable auto updates for Chrome? Once you run it, no need to keep packaging/updating Chrome, since it does it automatically on the client:

https://github.com/hjuutilainen/adminscripts/blob/master/chrome-enable-autoupdates.py

#!/usr/bin/env python

# encoding: utf-8

"""

chrome-enable-autoupdates.py



This script enables system wide automatic updates for Google Chrome.

It should work for Chrome versions 18 and later. No configuration needed

as this is originally intended as a munki postinstall script.

i want to do something similar for Google Chat. The one I modified from a chrome download pulled down the chat dmg from google but when I launch the app, it says to check with the developer to make sure it matches the OS. Delete that version then manually download from Google, then drag into the applications folder, then launch and it is happy. After it is happy, I deleted the app and ran my script again. This time it says it cannot verify the developer.

.

@gldc on your set up what Package and other scripts are you running?

Thanks, @ellavader . I used your script (with the DownloadURL="$4" modification).

When I first tried it, I got an error about curl not supporting https. I tried it with the Chrome URL you included as parameter 4. Tried it both with and without quotes (in the parameter field), and neither worked.

What did work was using single quotes, like so: 'https://dl.google.com/chrome/mac/stable/googlechrome.dmg'

I mention this in case anyone else runs into that problem.

As a small addition, I had to modify a line in ellie's script for OS X 10.14 (not sure if it affects other versions as well):

cp -pPR /tmp/jamf/mount/*.app /Applications || :

needs to be

cp -a /tmp/jamf/mount/*.app /Applications || :

Otherwise it messes up the permissions of existing Chrome installations.
Thanks for the awesome contribution!

@swhps I was running into similar issues as you, but finally determined the issue was how the Chat app was being copied to the Applications folder. I wasn't having any luck with ditto, but was finally able to open Chat when using cp. Additionally, I modified the curl request to handle the URL redirect.

Thanks for sharing this script! Has anyone run into an issue where Chrome can't update when deployed this way? What is a proposed workaround? I assume it might have something to do with user permissions / rights from when it was installed. Thanks!

@cornwella : Do the permissions problem you fixed prevent Chrome from updating itself?

If so, then @pds.jamfadmin needs to make the change you recommended.

you can deploy Chrome once and use a configuration profile to force auto updates. Also, curl scripts as root on all your endpoints is a security risk, FYI

@tlarkin As long as curl is using https, then a MITM attack becomes less of a concern. However, if Google were hacked and a bad copy of Chrome were sneaked in, then there would be a problem - a BIGGER problem. Anyway, just a point to consider. YMMV... ¯_(ツ)_/¯

@caine.horr only if the cert is pinned, which isn't every CDN or host is. That is the only the time MITM is not gonna work. Your results will vary.

first off, there is some great info in this post, thanks to everyone who has contributed. has anyone tried using this script to deploy chrome update on a machine where an older version of chrome is currently open/running? when i try to do so, the update goes through successfully, but then when i exit out of the running instance of chrome, i can't seem to reopen chrome at all until a reboot. if i try to run the app before rebooting, the chrome icon just bounces up and down on the dock but nothing launches. once i reboot, i am able to open chrome and it gives message that it closed unexpectedly last time, but it is on the new version and works fine. wondering if this is possible at all to deploy while chrome is running or if we will need to ensure users close out of the app first before deploying.

@dancunn typically you can install apps over running apps and it will mostly work, but there is always a risk of failure. So, to be safe, you should attempt to quit the app first. I have a script that will quit and run a policy to patch an app using NSRunningApplication and bundle IDs, found here.

Hopefully this helps

Today I'm revisiting @ellavader 's excellent script. I'm still a huge fan, but…

Today I was troubleshooting some Jamf stuff, and so I was manually invoking a policy that included this script. (using a custom trigger)

And in so doing, was able to "watch" it execute, and noticed this:

installer: Error - the package path specified was invalid: '/tmp/jamf/mount/*.pkg'.

Okay, so the attempt to install as a pkg failed because it wasn't a pkg. Should we care?

We could edit the script to check if the DownloadURL ends with .pkg, or .dmg, or .zip, and only attempt to execute the relevant code.

I'm not a pedant, and I don't want to waste time hiding error messages that no one will see, if it doesn't affect the results.

So, does it matter? Or is worrying about it a waste of time?

Hello all. I have been happily using the script by @cainehorr It has been working great. However it seems the link for the download no longer works. Does anyone have an updated link to continue using this scipt?

You're using https://dl.google.com/chrome/mac/stable/GGRO/googlechrome.dmg? It works fine for me. What happens if you access it in a browser? Are you getting a valid cert?

I had an older link which no longer exists. I updated the link and all is well... Thank you! @cbrewer

We have this script that goes out once a month and checks the current version to the latest google version. It just went out and started the update to version 78.xxxx. Worked great for us.

Hello. My organization is using this script too (v1.1 at the top of the thread.) But I'm having to reevaluate this because it installs on our MacBooks with auto updates broken. Is anyone having this issue too?

My preference is finding a solution where Chrome is installed with auto updates turned on. Can anyone assist with this?

We are using a single policy with the following 2 scripts to install the latest version of Chrome, and configure automatic updates...

Install:

#!/bin/sh



dmgfile="googlechrome.dmg"

volname="Google Chrome"

logfile="/Library/Logs/GoogleChromeInstallScript.log"



url='https://dl.google.com/chrome/mac/stable/GGRO/googlechrome.dmg'





/bin/echo "--" >> ${logfile}

/bin/echo "`date`: Downloading latest version." >> ${logfile}

/usr/bin/curl -s -o /tmp/${dmgfile} ${url}

/bin/echo "`date`: Mounting installer disk image." >> ${logfile}

/usr/bin/hdiutil attach /tmp/${dmgfile} -nobrowse -quiet

/bin/echo "`date`: Installing..." >> ${logfile}

ditto -rsrc "/Volumes/${volname}/Google Chrome.app" "/Applications/Google Chrome.app"

/bin/sleep 10

/bin/echo "`date`: Unmounting installer disk image." >> ${logfile}

/usr/bin/hdiutil detach $(/bin/df | /usr/bin/grep "${volname}" | awk '{print $1}') -quiet

MrRoboto, your script on Github totally worked for me. Automatic updates in Chrome are working. Thanks a million.

When i run the Github script i get the following, am i doing something wrong?
Keystone installed
AutoUpdateChrome.sh: line 51: /Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/MacOS/ksadmin: No such file or directory
Error: Failed to register Chrome with Keystone - code 0

@ralvarezOES That's good to hear. It's not my script, created by @ryan.ball

@Dylan_YYC What version of Chrome are you testing? The script only works for 75+
