Description:
When installing EDI 6.6 on Redhat linux 6.5, the Installer fails with the following exception,  "Unable to create the symlink".
Symptoms:
EDI 6.6 Installer fails with the following exception " Unable to create the symlink" thrown in the command prompt 
Cause:

This issue is probably caused by a missing lsb_release executable under the usr/bin directory. The executable should be installed if you have the redhat-lsb package installed in the operating system. The lsb_release executable prints certain LSB (Linux Standard Base) and Distribution information. The following is an example 

*******

[root@localhost bin]# ./lsb_release

LSB Version:    :core-3.1-amd64:core-3.1-ia32:core-3.1-noarch:graphics-3.1-amd64:graphics-3.1-ia32:graphics-3.1-noarch

*******

 From the Tibco side you can confirm this issue by verifying the installer logs under the .Tibco_home folder.  The following is a sample log of the exception found in the installer log.

*******

"BuildException encountered while running ANT target: create_symLink::Execute failed: java.io.IOException: Cannot run program "lsb_release" (in directory "/local/app/tibco/bc/6.2/protocols/tibedi/setup"): java.io.IOException: error=2, No such file or directory, class com.tibco.installer.util.TIBCOAntTaskRunner"

*******

Installing the Redhat-lsb package on the operating system should resolve this issue. Contact your Linux Administrator before performing this installation. 

On RedHat and RockyLinux installations, you can install this package by installing these two packages with these commands:

sudo dnf install -y epel-release
sudo dnf install -y lsb_release
