Symptom: On UNIX-based systems, during the installation process, retrieving and encrypting information from the password file results in an error such as the following:
Reading data from file path-of-password-file and encrypting it ... ***ERROR: Installation failed due to the following error - (Invalid empty password specified.).
Where path-of-password-file is a placeholder representing the path to a file from which the system is attempting to retrieve the password.
Possible Causes: The crypt_util program does not have executable permissions. Ensuring that this program has executable permissions is a step that should be performed prior to installation.
Possible Solution:
Add executable permissions to the crypt_util program as described in To Prepare to Install the Apache HTTP Server 2.2 Agent.
Remove the Agent_00x directory, presumably Agent_001.
Install the agent.
