Caution: When performing sudo installs, use sudo –i to ensure the proper use of environmental variables.

Caution: During the installation process, Tenable Security Center produces a log file in a temporary location: /tmp/sc.install.log. Once the installation process finishes, the file is stored here: /opt/sc/admin/logs/install.log. Do not remove or modify these files; they are important for debugging in case of a failed installation.
