My testing is on 10.14.4 machines.
I have attached screenshots for the two policies. Both policies are scoped the same!
Followed everything to the T with the c9wwh /macOSUpgrade script (Thanks for this!) but one problem. And we've noticed this mostly on the Sierra machines we are trying to upgrade to Mojave. Right when its about to restart to install, we get this:
Anyone else seen this?
@mm2270 I do not have it hardcoded in the script, but it is passed using the variable in the policy. I just copied and pasted the Jamf script from github. I used this last year with a Mojave installer without issue. Just trying to figure out what I'm missing.

# This script was designed to be used in a Self Service policy to ensure specific
# requirements have been met before proceeding with an inplace upgrade of the macOS,
# as well as to address changes Apple has made to the ability to complete macOS upgrades
# silently.
#
# REQUIREMENTS:
# - Jamf Pro
# - macOS Clients running version 10.10.5 or later
# - macOS Installer 10.12.4 or later
# - eraseInstall option is ONLY supported with macOS Installer 10.13.4+ and client-side macOS 10.13+
# - Look over the USER VARIABLES and configure as needed.

# APS Updates added 11/28/2019
#
# Updated "validate_free_space" to work with Catalina – freeSpace
# Added "Print :APFSContainerFree"
# /usr/libexec/PlistBuddy -c "Print :APFSContainerFree" /dev/stdin <<< "$diskInfoPlist" 2>/dev/null || /usr/libexec/PlistBuddy -c "Print :FreeSpace" /dev/stdin <<< "$diskInfoPlist" 2>/dev/null || /usr/libexec/PlistBuddy -c "Print :AvailableSpace" /dev/stdin <<< "$diskInfoPlist" 2>/dev/null
#
# Updated loopCout to work with Stub/Lite installer – Stub/Lite installer does not specify a macOS version.
# Check to see if the installer version matches, or if the installer does not have InstallInfo.plist.
# if [ "$currentInstallerVersion" = "$installerVersion" ] || [[ ! -e "$OSInstaller/Contents/SharedSupport/InstallInfo.plist" ]]; then
#
# Updated variable "currentUser"
#
# # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # #

# USER VARIABLES
# # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # #
## Specify path to OS installer – Use Parameter 4 in the JSS, or specify here.
## Parameter Label: Path to the macOS installer
## Example: /Applications/Install macOS High Sierra.app
OSInstaller="$4"
## Version of Installer OS. Use Parameter 5 in the JSS, or specify here.
## Parameter Label: Version of macOS
## Example Command: /usr/libexec/PlistBuddy -c 'Print :"System Image Info":version' "/Applications/Install macOS High Sierra.app/Contents/SharedSupport/InstallInfo.plist"
## Example: 10.12.5
installerVersion="$5"
installerVersionMajor=$( /bin/echo "$installerVersion" | /usr/bin/awk -F. '{print $2}' )
installerVersionMinor=$( /bin/echo "$installerVersion" | /usr/bin/awk -F. '{print $3}' )
## Custom Trigger used for download – Use Parameter 6 in the JSS, or specify here.
## Parameter Label: Download Policy Trigger
## This should match a custom trigger for a policy that contains just the
## MacOS installer. Make sure that the policy is scoped properly
## to relevant computers and/or users, or else the custom trigger will
## not be picked up. Use a separate policy for the script itself.
## Example trigger name: download-sierra-install
download_trigger="$6"
## MD5 Checksum of InstallESD.dmg – Use Parameter 7 in the JSS.
## Parameter Label: installESD Checksum (optional)
## This variable is OPTIONAL
## Leave the variable BLANK if you do NOT want to verify the checksum (DEFAULT)
## Example Command: /sbin/md5 /Applications/Install macOS High Sierra.app/Contents/SharedSupport/InstallESD.dmg
## Example MD5 Checksum: b15b9db3a90f9ae8a9df0f81741efa2b
installESDChecksum="$7"
## Valid Checksum? O (Default) for false, 1 for true.
validChecksum=0
## Unsuccessful Download? 0 (Default) for false, 1 for true.
unsuccessfulDownload=0
## Erase & Install macOS (Factory Defaults)
## Requires macOS Installer 10.13.4 or later
## Disabled by default
## Options: 0 = Disabled / 1 = Enabled
## Use Parameter 8 in the JSS.
## Parameter Label: Upgrade or Erase (0 or 1)
