microsoft-office uninstall fails with Permission denied @ dir_initialize

[navneetkarnani]

I had microsoft-word, microsoft-excel and microsoft-powerpoint installed individually.

When I tried upgrading microsoft-powerpoint yesterday, it failed to uninstall with a error that looked similar to:
Permission denied @ dir_initialize - /var/folders/vf/937rsb3s7p57123chvtk8jbh0000gn/T

I checked the directory, and it is owned by the non-logged-in user

So, I manually removed it using the command:
/usr/bin/sudo -E -- /usr/sbin/pkgutil --forget com.microsoft.package.Microsoft_PowerPoint.app

And then installed microsoft-office

Today, when I ran: brew upgrade --greedy
the process failed at uninstalling microsoft-excel with a similar error.

I can't delete, change permission or ownership of the directory /var/folders/vf/937rsb3s7p57123chvtk8jbh0000gn/T, even as the user, because I see a Permission Denied message. When I looked at the directory, looks like it contains application level settings

I got around this, again, using the "forget" command above. But I need to find the cause.

What is happening ? What is breaking this ? How do I fix it ?

Does it have something to do with the fact that I installed the applications using the su - authoriseduser shell from within the owner user ?

At this time, I am manually uninstalling all the applications, and trying again. Will keep you posted if I have new findings.
