Did I miss something so that it couldn't detect the server distro?
Thanks.

I had the same problem when installing the version from the master branch
I switched to tags/v0.15.9 and rebuild vuls, now it works

Thank you very much, now I bypass it with your methods. :-)

Hi, @ZhixiongChi @rtuk

I cannot reproduce the problem.
I want to investigate and fix it, so please try running it with the -debug option.

./scan.sh --debug.

[rtuk]

@kotakanbe
I have tried this before changing the branch from master to the latest tag, it did not provide me with any further information
FYI, it seems @ZhixiongChi is running vuls in docker, I am running vuls as a standalone install on a server without using docker

I had the same problem and same output and debug info with @rtuk . I installed Vuls by following the tutorial from vuls.io .Did I miss something?

I tried to read the code, and I found that the reason for this error was that I did not get the required information from the TOML configuration file. Is there something wrong with my TOML file configuration? I've already posted my toml file.
By the way, there is some error info
Error loading /root/go/src/github.com/future-architect/vuls/scanner/config.toml If you update Vuls and get this error, there may be incompatible changes in config.toml Please check config.toml template : https://vuls.io/docs/en/usage-settings.html

[kotakanbe]

Hey guys.

I still can't reproduce it.
If you use vulsctl or docker-based vuls, be careful in config.toml.
If you specify localhost in config.toml, Vuls will scan for Vuls docker containers.

Please read the manual carefully.

To view the detail, vuls tui is useful.
To send a report, run vuls report -h.

[HsinTsao]

I did not use the vulsctl or docker, and I installed it manually, but I still have the problem. I will try to switch to tags/v0.15.9 and rebuild vuls

[kotakanbe]

Hi, @HsinTsao

Plz scan with --debug option and paste here the output.
（Make sure no sensitive information.）

./vusl scan --debug

If you paste the -debug output, I may be able to help you.
