Resolution

The Axway Installer uses the /tmp folder for storing temporary files, which are used only during the time of the installtion. The above error is being thrown because the Installer doesn't have the necessary permissions to write in the /tmp folder.

The solution is to configure another folder for storing the temporary files generated by the Installer. By setting the environment variable TEMPORARY_DIR to point to another folder where we have all the permissions in place, we can install the patch without any issues.
