Munki2: MSC launch exception when InstallInfo file missing #302

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Upon trying to reproduce another issue, I decided to wipe the slate and 
completely remove /Library/Managed Installs.

What steps will reproduce the problem?
1. rm -rf "/Library/Managed Installs"
2. launch MSC via the CLI
3. exception below:

What is the expected output? What do you see instead?

I worked around this by falling back to an empty list for 
getInstallInfo().get():
