Im getting the following error when running my SUS policy on some Macs, has anyone seen this before? Mr Google can not find anything

I'm getting this exact same error. Didn't happen on one computer, but happened on another one.

[jthurwood]

Ive got this happening on a bunch of machines. Ive had to temporarily disable my SUS policy until i can get it fixed.

[jthurwood]

Has anyone else seen this?

[jthurwood]

@jkuo Did you manage to find a fix?

[jkuo]

@jthurwood - nope, not yet. It's intermittent for me, so I'm not sure what's going on.

[Look]

We had a bunch of machines with something funky going on with the cache files that was causing this.
Try clearing the caches in terminal
sudo rm -rf /var/folders/*
Then restart and try the update again fixed it pretty much every time.
Just be careful running it because sudo rm -rf will blitz anything it's told to no questions asked so make sure you have it right. This was almost exclusively 10.9.2 and 10.9.3 machines for us, pretty sure there is some bug with the cache clearing etc...

Edit: Just remembered where it came from, this was originally the fix for the "unauthorized caller" errors a while back, but it worked for this type of issue as well.

@Look I'm seeing this issues as well.

Rather than having the SUS fail, remove /var/folders/*, restart, and run SUS again. Has anyone tested removing these folders using a "before" script in conjunction with the SUS Policy?

Thanks! ;)

[Look]

When I was testing originally I found behaviour was somewhat unreliable if you didn't restart the machine. There are probably other references to the files that don't clear until you restart.

Running JSS 9.6.5 and seeing the this issue with the latest OS X security updates. Anyone have a specific fix?

[RobertHammen]

Are you doing a force restart at the end of the policy (not "if an update requires it")?

[corbinmharris]

Only "if an update requires"

[gskibum]

I'm seeing this with 5 different JSSs running 9.6.5. with a policy using softwareupdate -da to cache packages.

It seems Yosemite devices don't have this issue. Just Mavericks and older.

sudo rm -rf /var/folders/* followed up with a reboot didn't help.

Any solutions?

Edit: It isn't restricted to just the latest security update. On one system the security update along with the Safari update were waiting. I applied just the security update so only the Safari update was left. And the error remained when trying to cache again.

I'm seeing this too with 9.81 on OS X 10.11.4.
It really interferes with other packages getting installed. I have to do a killall softwareupdate to kill the process and packages installed via policies can then get installed successfully.

I understand why inventory runs the softwareupdate command because we have it set to collect it on recon/inventory collection. But how is it running that command that it's causing this error?
