Upgrade from 12.0 Build 12004 to Build 13000

Hello,

We are trying to upgrade to the next SD version, and are having problems running the commands.
- Current version and build: 12.0 Build 12004
- Next version and build: 13000
- Two migrations away from latest 13002
- Have downloaded the ppm (linux) file to the BIN folder of a TEST SD server
- When running the UpdateManager.sh script, there is no response
- The UpdateManager tool is not coming up to browse to the ppm file (see attached)
- Have also tried the UpdateManager command with option -c (for step by step guidance) and it does not work
- Please let us know what is wrong

Much appreciated for your time,
James
