MacOS Ventura Upgrade Issue

Also, I have tried deleting the file in question "Install_macOS_13.0.1-22A400.sparseimage" and then re-running the script but it fails with the same error.

I think it has to do with the Info.plist file being referenced, but I'm not sure where that file comes from.

So I re-read the documentation on erase-install and i thought maybe the --update flag was interferring so I changed the command line to this

Running command /Library/Management/erase-install/erase-install.sh --reinstall --os=13 --overwrite --current-user --min-drive-space=60 --check-power --depnotify

However, I still see the same error in the log

Result of command:

So this is the issue, it turns out. I deleted the "content" folder and it works as expected. Not sure what is causing this but I will be adding a line to remove that folder.

Great find!  This just started popping up for some of my users as well.  Some upgrades are working without issue, but some result in the error of the installer being invalid.  I'll try your method and see if that works.

Are you able to share the new script you used that ended up working out?

@AbeTechster, here is the script we use. This calls the SwiftDialog script and seems to work for us. It is the standard one most have found on GitHub with the two statements for deleting the damaged download and other previous installers. We have not received any additional failures related to the script. 

Hope this helps...

#!/bin/bash

This script was created on 12/12/22 to
address an issue with the upgrade download
process in erase-install where is creates
this folder. Then it starts the swiftDialog
process.
