Problem deploying McAfee EPO to bigsur

The installation fails when run via the jamf agent. When I run it via root, or sudo, it succeeds. Seems specific to bigsur as I don't have this problem on 10.14.x. Any suggestions?

Log:

Our proxy is blocking the gist.github.com site. Can you paste that here so I can take a look? What I am doing now is deploying the .sh file via pkg to /usr/local/bin, then trying to launch it from there. I'm not sure what I would do differently except change the working directory before launching.

So I put a "cd /tmp" above the install command and it worked. I had no idea the jamf agent/root used "/" as the home folder. I thought it was somewhere else.

Update: yep, that was it. The .sh was fine in /usr/local/bin, but the working directory had to be writable. Thanks for the help everyone!

What version of McAfee are you installing? Because I'm using the same general method of installing it by running a postinstall script in our package that drops the oh-so-wonderful McAfee install.sh file into a specific location and executing that. It's working fine on our Big Sur Macs as far as I can see.

EPO agent 5.7.3.245, released in June(I think). The previous version we deployed, released this spring, installed fine using the same method.

@MrP In Big Sur / is not writeable. You need to do something like @mm2270 suggests and wrap the McAfee install.sh file into a .pkg where you can run it from a location other than /. As an example, here a postinstall script I wrote for a .pkg that includes install.sh plus the ENS components: McAfeeENS10.7.1postinstall.bash. It's for an older version of McAfee, but should give you the idea.

Apologies for the formatting. Apparently the team re-designing the forum never considered that "Shell Script" should be one of the options for a code block. Grrrrrr

We do what @mm2270 and @sdagley do. Build your package with a postinstall.sh

We use '/Library/Application Support/McafeeBuild' or wherever BS can access

It's Six of one, half dozen of the other. I originally had a Jamf script running install.sh/McAfeeSmartInstall.sh, then moved to a postinstall (for the reason that was mentioned above: / is not writable in Catalina and newer OS versions). Now that I know that the Jamf script execution fail was due to / not being writable, i might be switching back...

Biggest difference in my mind is how much control the packager (person doing the wrapping of the agent) has to modify Jamf scripts. Some larger orgs have separation of duties (or rigorous change control), so it's good to use postinstall because then the packager knows exactly how the agent is going to be installed with no external dependencies on the MDM. Other smaller shops (such as mine) do it all by ourselves, so we have more flexibility with Jamf scripts and how to package.

PROTip: deploy the install.sh (or McAfeeSmartInstall.sh) to /tmp and then execute it from there. /tmp gets cleaned up after a reboot.

Yeah, I just opened up Composer and looked at mine...been a minute and indeed, we use /private/tmp as well. No issues now or prior.

Does anyone know what this means. i have tried the method of moving the McAfeeInstall.sh into the /tmp directory. When i run it, it launches and get stuck here.

PackageKit: Enqueuing install with framework-specified quality of service (utility)

i do not know what this means. btw this is running locally and using Jamf

I've moved companies and my new org uses McAfee. I'm not familiar with McAfee and Mac, and looking over bits of documentation and posts here and there, I'm wondering if all I need to do is package up the install.sh and deploy it via policy, for the agent install? No changes needed to the script? What is the ripoff.sh script?
