Big Sur upgrade deployment issues

Can't seem to figure it out

@rpayne I'm having the same issue with macOSUpgrade.sh script. I'm going to manually step through the script to see if I can figure out the issue.

@rpayne In the script macOSUpgrade.sh line 66 the parameter 5, which is the version of the OS, is passed from Jamf.

installerVersion="$5"
installerVersion_Full_Integer="$( /bin/echo "$installerVersion" | /usr/bin/awk -F. '{ print ($1 * 10 ** 4 + $2 * 10 ** 2 + $3 )}' )"
installerVersion_Major_Integer=$(/bin/echo "$installerVersion" | /usr/bin/cut -d. -f 1,2 | /usr/bin/awk -F. '{for(i=1; i<=NF; i++) {printf("%02d",$i)}}')

I have it set to 11.2.2. In the while loop starting at line 389 and ending at line 440 the following line of code are used to get the version of the downloaded OS installer:

if [ "$installerVersion_Full_Integer" -lt 110000 ]; then
                currentInstallerVersion=$(/usr/libexec/PlistBuddy -c "print 'System Image Info:version'" "$installerPlist")
else
                currentInstallerVersion=$(/usr/libexec/PlistBuddy -c "print DTPlatformVersion" "$installerPlist")
fi

Manually checking /Applications/Install macOS Big Sur.app/Content/Info.plist DTPlatformVersion is 11.2. The if statement at line 405:

 if [ "$currentInstallerVersion" = "$installerVersion" ]; then
            /bin/echo "Installer check: Target version is ok ($currentInstallerVersion)."

Is never true, since 11.2.2 != 11.2. So the script does the download function repeatedly until it reach the maxTrialCount and fails. I checked and if I set parameter 5 to 11.2 the upgrade script works. Looking in Info.plist there isn't a string that has the minor release, i.e 11.2.2 to compare against.
