Errors When Deploying in Jamf - Intel & Apple Silicon

[jonidaher]

Hello, this is a great workflow, and I'm very grateful to Graham for providing it for us all. However, I'm having some issues on some devices. Hoping someone knows what's going on.

I've been testing upgrading machines from Big Sur to Monterey using the erase-install.sh package with the following arguments:
--force-curl --reinstall
The full line in Files & Processes is this: /Library/Management/erase-install/erase-install.sh --force-curl --reinstall

Intel machines - Worked very well in three or four, but a couple keep returning this error:

ERROR: downloaded installinstallmacos.py does not match checksum. Possible corrupted file. Deleting file.
Could not download installinstallmacos.py so cannot continue.
[erase-install] 'caffeinate' ended

Apple Silicon machines - I've tested on two machines. The process asks for administrator credentials and then the screen-wide banner appears. However, the upgrade doesn't succeed. This is the error in Jamf:

Preparing: 43.7%
Preparing: 43.8%
Preparing: 100.0% An error occurred preparing the update.
[erase-install] 'Self Service' ended
[erase-install] 'caffeinate' ended
/Library/Management/erase-install/erase-install.sh: line 945: 37028 Terminated: 15 /usr/bin/caffeinate -dimsu -w $pid
[erase-install] 'jamfHelper' ended
/Library/Management/erase-install/erase-install.sh: line 724: 37101 Terminated: 15 "$jamfHelper" -windowType $window_type -title "${!dialog_reinstall_title}" -heading "${!dialog_reinstall_heading}" -description "${!dialog_reinstall_desc}" -icon "$dialog_reinstall_icon"

I have run the policy several times on each device that has failed. Please let me know if you have any ideas. Thank you.

Make sure you have the latest version of the script to prevent the checksum error.

If you get the "error preparing the update", unfortunately you have to start again. It means the download got corrupted.

[jonidaher]

Please bear with me, as I'm relatively new to all this. I thought adding the --force-curl argument meant that I was always grabbing the latest script.

[grahampugh]

Do you have the latest erase-install.sh though?

[jonidaher]

I think so. I got it from here 7-10 days ago: https://github.com/grahampugh/erase-install/releases
And as I mentioned, it does work on some machines.
