When You Have Trouble Installing or Updating the Scanner#

When You Need Help

This page explains what to do when you run into trouble installing or updating the scanner (a small program that collects the list of software installed on a server and sends it to FutureVuls).

Check These First#

Common Causes and Solutions#

A. Installation with yum fails

The installation script uses yum or apt, so problems with these tools can cause it to fail. You can install manually with rpm instead.

  1. Run only the first half of the installation command to save the script (curl -sO https://installer.vuls.biz/vuls-installer.sh).
  2. Refer to installPkg() in the script and install the required packages manually with rpm or a similar tool.
  3. In case "inst" inside the script's main(), delete the installPkg line.
  4. Set the environment variables for your environment, and run bash ./vuls-installer.sh inst.
B. A cache is created in /var/tmp/ during installation

This is how the Linux scanner works. Switching to offline scan stops the cache from being created. However, the "Updatable" and "Latest Version" columns will no longer show information (this does not affect the number of vulnerabilities detected).

C. I want to keep the scanner up to date

AUTO_REFRESH_BINARY=true in the installation command enables automatic updates. We recommend keeping it. For how to update manually, see Updating the Scanner.

D. I want to confirm that the uninstallation succeeded

If the uninstall command finishes without errors, it succeeded. To check manually on Windows, confirm that C:\Program Files\vuls-saas no longer exists and that vuls-saas-scan is no longer in Task Scheduler.
