Checksum is Not Valid: Parameter 7 is Blank #147

Closed MusicMaker81 closed 3 years ago

MusicMaker81 commented 4 years ago

Thanks for this script. I want to use this to upgrade to Catalina. When running the script it does run the trigger and downloads the macOS installer. It ends with an error. Jamf reports: macOS Installer Downloaded 3 Times - Checksum is Not Valid

I left 'Paramater 7' Blank because I didn't want to verify the checksum. So why does it report that the checksum is not valid? I also tried it by entering the right checksum but that also failed with the same error.

You can fix this by changing if [ -n "$installESDChecksum" ]; then to if [ "$installESDChecksum" != "0" ]; then and replace the empty value with 0 or to an actual hash if you want to use the feature.

I have applied this change, both the code change and I replaced parameter 7 with a 0 and I still get "checksum is not valid." is there another way I could bypass the checksum error?

@RiversideKid there is most likely a syntax error somewhere in the script from modifications or how it was copied. However, if you want to disable the checksum check, you can try commenting out line 363 of the latest version. If that doesn't work, you'll also want to comment out lines 371-374, but just 363 should be fine.

I have tried the line 363 371-374 and I still get this. macOS installer downloaded 3 times - checksum is not valid @kc9wwh

This worked for me. The only thing is that the policy still downloads the macOS installer twice. I don't know why, but the pop-up with 'downloading' appears twice. When looking at the Activity Monitor you can also see that it is going to download a second time.
