Oddly enough I was thinking about this earlier. Thank you.

I'll try it out.

Version 12.3.0 broke some things with the script. Mainly, it sees the version as "12.3" instead of "12.3.0", so I added a check around line 184 to check for this specific version, and add ".0" after. I also tidied up the download url to look for the string between the double quotes, instead of counting characters (line 211).

I can't get this script to work for me. It always thinks Citrix is in use and won't proceed. Even when the app isn't in use there is always something active from Citrix in the Activity Manager. I have played with the script and even tried removing the in use checks but it still won't install. Is anyone else using this or have something better?

I'm currently running Citrix Receiver 12.1.100 and need to update to 12.4. I would rather have the script kill Citrix on it's own instead of requesting the user to do something.

Is the reported download link valid? It should be in the log.

bmonroe · ‎05-31-2017

They changed the website... You need to replace the line that sets url2. This will work as a work around:

url2=`curl -s -L https://www.citrix.com/downloads/citrix-receiver/mac/receiver-for-mac-latest.html#ctx-dl-eula-external | grep dmg? | sed 's/.*rel=.(.*)..id=.*/1/'`

The original author also hard coded a minor version add with 12.3 (so it would become 12.3.0) so I added some regex for that check so it'll match the installed version for everything else (12.5 becomes 12.5.0) Below is the relevant section that needs to be changed:

    # Get the latest version of Receiver available from Citrix's Receiver page.
    latestver=``
    while [ -z "$latestver" ]
    do
        latestver=`curl -s -L https://www.citrix.com/downloads/citrix-receiver/mac/receiver-for-mac-latest.html | grep "<h1>Receiver " | awk '{print $2}'`
    done
    if [[ ${latestver} =~ ^[0-9]+.[0-9]+$ ]; then
        # Missing minor version to match the installed version, so we’ll add it here. 
        latestver=${latestver}.0
    fi
    echoFunc "Latest Citrix Receiver Version is: $latestver"
    latestvernorm=`echo ${latestver}`

Error running script: return code was 1.

stevewood · ‎06-24-2017

@khuong_lai because the script uses Bash exit codes to tell what it has done, and the author chose to use exit code 1 to show a successful install, the JSS will always see it as a failed script. Any exit code other than 0 will be seen as a failed attempt by the JSS, as the JSS expects exit code 0 for success.

Rather than using exit codes, the script should probably be modified to write to an EA via the API, or write to a PLIST file that is then read by an EA, or simply echo some text with what was found.

At any rate, something other than exit codes should be used, or users of the script just need to know a failure isn't necessarily a failure.

I had an issue with "Citrix appears to be running" - it always showed up even if the receiver was not running. Then I realised, that ps aux also found different processes. So I changed this module of the script as follows:

# Check to see if Citrix Receiver is running
receiverRunningCheck () {
    processNum=$(ps aux | grep "Citrix Receiver.app" | wc -l)
    if [ $processNum -gt 0 ]
    then
        # Receiver is running, prompt the user to close it or defer the upgrade
        receiverRunning
    fi
}

With this changed module the workflow works for me 🙂 btw. thank you for the script

Has anyone had any luck using this script to perform a clean install of Citrix Receiver 12.7?

ericjboyd · ‎09-18-2018

Citrix Receiver has become Citrix Workspace.

Any suggestions on how to modify the script to include this new version?

peter_wreiber · ‎09-19-2018

I have made some quick modifications to the script to support Citrix Workspace . Seems to install ok, but It throws an error 3 at my end.

@peter.wreiber I think Citrix have changed things again.

curl -s -L https://www.citrix.com/downloads/workspace-app/mac/workspace-app-for-mac-latest.html#ctx-dl-eula-external | grep "<h1>Citrix " | awk '{print $2}'

returns Workspace as the full line returned is

<h1>Citrix Workspace app 1809 for Mac</h1>

'{print $4}' gives the version now.

If suppression is a requirement, good to see these settings are now where hey belong, at the computer level:

#!/bin/sh

/usr/bin/defaults write /Library/Preferences/com.citrix.receiver.nomas AutoUpdateState -string Disabled
/usr/bin/defaults write /Library/Preferences/com.citrix.receiver.nomas HockeySDKAutomaticallySendCrashReports -bool false
/usr/bin/defaults write /Library/Preferences/com.citrix.receiver.nomas HockeySDKCrashReportActivated -bool false

/usr/bin/defaults write /Library/Preferences/com.citrix.receiver.nomas BITApplicationWasLaunched -bool true
/usr/bin/defaults write /Library/Preferences/com.citrix.receiver.nomas CEIPEnabled -bool false

exit 0

...and yes, can use a Configuration Profile...pick yer poison. 🙂

Hi all,

Is it possible for someone to post the latest complete script version? without the Error 3 code.

I'am fairly new with JAMF and I will follow a course this february to get the hang of it.
I already know how to edit and make profiles and policies with adding scripts etc.

But my scripting skills are what you can call a complete beginner.
Luckily we have you guys 🙂

Thanks for the help.

Cheers,
Dennis

Hi all,

I am trying to get the Citrix Workspace up and running..

The thing is..... When I install the package via JAMF the Workspace app is not detected.. When I manually install the package all is working fine..

I am going nuts here..... Anyone any idea?

I have tried using this script
I have tried using the original installer
I have tried package made by Autopkr.

All with the same results.. Install is OK (no errors) but Workspace is not detected when starting the saas app. When I install the package interactively all is OK..

alexwaddell · ‎03-19-2019

Hi all,

After quite some wrangling I believe I have resolved the script errors - the joy of version numbers changing & needing to be padded and normalised...

Just saw someone else beat me to it

marklamont · ‎05-15-2019

@alexwaddell I'm going to delve into the script but I just tested it to do an install, which it performed ok but reported a fail

Wed May 15 04:42:47 : Newly installed version is: 19.3.1 Wed May 15 04:42:47 : Exit code: 3 - ERROR: Citrix Workspace update unsuccessful, version remains at 0000!

jwojda · ‎05-15-2019

looks awesome! Thank you for everybody's hard work!

marklamont · ‎05-15-2019

@dsmetham how about posting your script as well?

marklamont · ‎05-15-2019

So I got bitten by the bug on this one as I actually need it for a job and ended up with this version. It doesn't go the complexity of checking the version to 3 sub versions, as from what I can see the important bit is the first two. If Workplace is running then it simply tidies up and exits to await another try.
The exit codes are tweaked to only be 0 or 1 so jamf reports pass or fail correctly. expected results; no update required, update worked and workplace running all are pass for me. all others are fail.
here it is

Love this, and thank you.

I do see the following however:
Fri Aug 16 11:13:19 : Exit code: 3 - ERROR: Citrix Workspace update unsuccessful, version remains at Citrix Workspace 1903!

it seems to show fail no matter what.

Did something change not the URLS?

Thanks

@marklamont I ran your script on a fresh installed of OS X and it's telling me that Citrix is running but Citrix is not installed yet. Any idea?
