  java.io.IOException: Cannot run program "__PATH__/vmware-umds-distrib/vmware-install.pl": error=2, No such file or directory

   

• There is not perl executable binary at /usr/bin/perl in Linux OS where VCF Download Tool is running
  

  # ls -l  /usr/bin/perl
  ls: cannot access '/usr/bin/perl': No such file or directory

Environment

VMware Cloud Foundation 9.0

Cause

VCF Download Tool uses perl to install UMDS. So if perl executable binary is missing at /usr/bin/perl in the Linux OS, installing UMDS fails.

Resolution

Install perl to the Linux OS.
