Failed: Unknown OS Type

[benji1000]

Hi,

I successfully ran Vuls against one of my servers, but I have a problem when running Vuls against another one of my servers. When running vuls prepare, it fails with this error log:

INFO [localhost] Detecting OS... 
INFO [localhost] Detecting OS of servers... 
ERROR [localhost] (1/1) Failed: web, err: [Unknown OS Type]
ERROR [localhost] Failed to init servers: No scannable servers

The server I'm trying to scan is a standard Ubuntu 14.04. How come it fails to detect the OS version?

I saw in the code that the detection is based on this module, but I'm not familiar with Ruby nor the Go language. As far as I can understand, all the commands indicated in this snippet of code seem to output useful info. Should I report this to specinfra directly?

cat /etc/debian_version:

jessie/sid

lsb_release -ir:

Distributor ID: Ubuntu
Release:        14.04

cat /etc/lsb-release:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=14.04
DISTRIB_CODENAME=trusty
DISTRIB_DESCRIPTION="Ubuntu 14.04.5 LTS"

Thanks for your help!

Hi @benji1000

Please scan with --debug option to get detail information.

Thank you for your answer.

I added a user on the server I wanted to test using the useradd command, but I didn't specify a shell. Turns out, the default shell for my system was set to /bin/sh, and Vuls runs the command set -o pipefail, which is incompatible with /bin/sh, and requires /bin/bash as shell to work.

Re-creating the user using --shell /bin/bash option in useradd solved the issue.
