Question about location for lynis directory and its binary

[Aria-AAs]

I'm trying to install and use lynis on my Kubuntu 25.04 system from GitHub.
As much as I know this is an application which installs by user and not exist in default installation of kernel, so I tried to put it in the /opt/lynis and due to this fact that this is an administration application I give access of the /opt/lynis to root:root recursively and give the /opt/lynis/lynis a 750 permission using chmod command. At last, I made a symbolic link to /opt/lynis/lynis at /sbin/lynis. Then, when I ran the command sudo lynis audit system, it fails with this error. (Error does not handle \n as a scape character as intended and echo it instead)

> sudo lynis audit system
\nFatal error: can't find include directory\nMake sure to execute Lynis from untarred directory or check your installation.%

Based on my understanding of this error, I tried to run lynis from its directory directly. So I tried:

> cd /opt/lynis
> sudo ./lynis audit system

Then it ran correctly.
It is not that hard to run it in this way, however I prefer to run it without ./ and no matter from which directory.
So my approach was making an executable file at /sbin/lynis contains this content:

#!/bin/bash
cd /opt/lynis
./lynis "$@"

Now I can run it using this command straight:

sudo lynis audit system

I have two questions.

• Is my idea about put lynis directory in /opt and its binary file in /sbin correct?
• Is that approach to make another binary file to change directory and then run lynis from there is a good idea?
  • If not so, what could be better?

Using the version from GitHub is perfectly fine, but it looks like you are aiming for a normal installation. If you are installing it this way, then it is probably better to use the latest version of Lynis as a normal package. Then everything is arranged for you, including setting up the right location(s).

Thanks for your response.

Using the version from GitHub is perfectly fine.

I did not mean that GitHub version of lynis has any problem. It is totally fine as you said and that is why I aim to use it.

but it looks like you are aiming for a normal installation.

I tried using the stable version installed using apt package manager and that was fine as well, now I want to use the GitHub version for various reasons.

I just simply want to know about those questions.
