I have been using the erase-install.pkg successfully for some time, placing it within Self-Sevice and allowing users to install at their convenience. However, with one user, I have run into an issue where is appears that the step of grabbing the latest installer is failing.

Background:

This particular user attempted to install Ventura on their own through Software Update within System Preferences. It looks like the installer was downloaded, however they were blocked when they reached the prompt requiring an administrator to allow the installation.

I directed them to Self Service where the erase-install.pkg is loaded (28.0). The attempt to install, the progress wheel begins to spin for a bit, stops, and nothing is installed.

Log

Taking a look at the applications installed on this user's machine, it looks like they have an older version of the installer present (Install macOS Ventura.app 18.0.02) likely from when the first attempted their own update. The script sees a newer version, but something prevents it from moving forward.

Here is the History log from the failed Self-Service attempt:

 Any ideas as to what I can do to resolve this?

Thanks!

I'm having a similar issue but haven't had time to do much digging. It is related to mist but the quick fix is to delete the old installer first. This isn't a great solution if you are checking frequently but if your goal is to just make sure that your Macs have 13.2.1 then this will resolve it

@gk96_2 To avoid the code path in erase-install with the failure do not use the --update option to check for a newer build.

Without that option you will need to delete any existing macOS installer that's not the version you want prior to running erase-install otherwise it will use the old installer. You can find the version numbers for the Install macOS apps on @ClassicII 's web site, specifically on the https://mrmacintosh.com/macos-12-monterey-full-installer-database-download-directly-from-apple/ and https://mrmacintosh.com/macos-ventura-13-full-installer-database-download-directly-from-apple/ pages, then create a Smart Group where the criteria matches the app name and a version number not the same as the version you want to install, then use that Smart Group as the Scope for a Policy that will delete the  old macOS install apps.

You might also want to update the version of erase-install you're using to 28.1 although to be clear erase-install calling mist-cli to check for newer installers has problems in 28.1 as well.

EDIT: erase-install 29.0 is out. Looking at the changes from 28.1 I do not believe it has any changes that would prevent the failure being see with the --update code path in 28.0/28.1, but ¯\\_(ツ)_/¯ it may be worth a try.

Thanks @sdagley .

Do you mean in this particular instance, or in general?

I am using it based on this:

--update

If the --update parameter is used, and an installer application is already cached on the system, the script will compare the version of the cached system with the installer that is available from Apple's catalogs. If a newer version is available, the cached installer is removed and the latest version is downloaded. Nothing is downloaded if the versions are the same or the cached system is newer (for example there is a cached beta installer).

@gk96_2 In general. While erase-install 28.1 has changes related to mist and the --update option it's still not working in some cases. What triggers that isn't known yet, and while it's been reliable using --update on my test Macs the failure rate in the field for my users has been high so I've changed my workflows that use erase-install to not use the --update option, and run a pre-flight script that deletes any existing Install macOS app if it's not the version I want installed.

Just an update to this issue:
I deleted the Ventura install application from the machine, update my erase-install package to 28.1, and attempted to run the update. Unfortunately, it failed again.

One thing to note is that I did forget to remove the --update parameter as sdagley suggested. unsure if that would have made a difference.

To close off this thread, @grahamrpugh determined the cause of the error, and checked a fix in to the main branch of erase-install on 2023-02-16 (see https://github.com/grahampugh/erase-install/commit/a53e55f86c3e26afe5a775ba339c889fae90c081) so the next release won't exhibit this problem.
