Issues importing the Zoom.us plugin installer with munkiimport

[Kai Howells]

I'm seeing some strange behaviour when trying to import the Zoom.us plugin installer with munkiimport.

Zoom is a videoconferencing and chat service. The plugin can be downloaded from here: https://zoom.us/download

When I run munkiimport, it looks at the .pkg, tells me that there's no valid Distribution or PackageInfo found, but then it creates and launches ~/Library/Application Support/zoom.us/zoom.us

The output in Terminal is:

server:~ admin$ munkiimport /Volumes/Data/Munki/import/zoomusInstaller.pkg 

WARNING: No valid Distribution or PackageInfo found.

WARNING: pkginfo for 'zoomusInstaller' contains no installation check info!

    No useful receipts were detected, and no 'installs' items were provided.

    If you do not add an 'installs' item or an installcheck_script,

    Munki will have no way to determine the item's installation state.

    This can result in repeated installation attempts or failure to attempt

    installation at all.

    return raw_input(prompt).decode('UTF-8') or default.decode('UTF-8')

I suggest you use autopkg (https://github.com/autopkg/autopkg) to download and import Zoom into munki. 

autopkg search zoom shows there is a munki recipe for Zoom.

Which has two downloads. You said “plugin”, so I downloaded the “Zoom Plug-in for Microsoft Outlook”.

makepkginfo doesn’t complain:

…and neither does munkiimport.

So let’s try the _other_ download..

makepkginfo ~/Downloads/zoomusInstaller.pkg 

WARNING: No valid Distribution or PackageInfo found.

WARNING: pkginfo for 'zoomusInstaller' contains no installation check info!

    No useful receipts were detected, and no 'installs' items were provided.

    This can result in repeated installation attempts or failure to attempt

    installation at all.

and what evil is this? An application _opens_… This is nasty stuff… Somehow just querying this package has triggered an install of some sort, because now there are files in ~/LIbrary/Application Support/zoom.us that were not there before.

This is scary stuff here.

More investigation is needed.

The zoomusInstaller.pkg, available from https://zoom.us/client/latest/zoomusInstaller.pkg, is evil.

It’s Distribution file contains an installation-check script. This is not unusual. What is unusual is that the installation-check script calls the preinstall script, which does the actual install. There is no traditional payload. Just examining this package to determine what will be installed ACTUALLY MODIFIES FILES.

Calling installer -pkginfo -pkg ~/Downloads/zoomusInstaller.pkg as a non-privileged user is enough to install the software. The preflight script also launches the stupid thing.

I don’t have any suggestions other than hollering at the vendor.

Just a quick follow up here — it turns out there is an Autopkg Zoom.munki.recipe that repackages the Zoom web browser plugin so it isn’t such a disaster.

autopkg run Zoom.pkg  will build a nice pkg, 

autopkg run Zoom.munki   will not only build a nice pkg, but it will also import it into your Munki repo.

Once again, Autopkg is the antidote to vendor installer poison.

Autopkg got a workable install of the main Zoom utility. But the OP referenced a plugin which is what is still giving me fits, specifically the plugin for Outlook.

Munkiimport appears to do its job with no difficulty on ZoomMacOutlookPlugin.pkg, and it shows up where I told it to in Managed Software Center, and invoking an install from there gives every appearance of having succeeded...that is, until you create a new meeting in Outlook and the Zoom icon isn't there.

But wait, there's more. If you install that package directly on a client Mac, by right-clicking it (it appears not to be properly signed, so you have to bypass Gatekeeper, in case that's significant, but then the same is true of the main Zoom installer pkg), it actually successfully installs, and Outlook commences behaving as desired. And now if you invoke Uninstall for it from MSC, that also does nothing! Outlook says it's still there, even though in MSC the Uninstall button has changed back to Install.

There doesn't seem to be a recipe for it on github; perhaps some darling soul could remedy that?

The package is located here:

https://zoom.us/client/latest/ZoomMacOutlookPlugin.pkg

The postinstall script is a bit of a disaster (note the lack of indentation is in the original).  The fact that it even mentions things in user space and has liberal sprinkling to tildes isn't a good sign.  If this is something you pay for, get the developer to assist with how to get it installed properly.  Otherwise the answer probably lies in here somewhere, likely around the gyrations to support both admins and non-admins installing the software.
