List installed kernels - Off topic tangent

Even when @Aravisian pointed out your error, by showing this...

You then demenstrate this behavior bellow...

You demonstrate the lack of ability to, admit when you are wrong, to take the correction, learn from it, and to not infringe again.

Regarding your 2nd point, yes I do expect one to read the posts, to be informed, before making a reply themselves. By admitting your lack of doing so, only demonstrates your ignorance, and by your behavior, arrogance.

Continue this behavior, and you will find yourself suspended, for not following the rules, and not correcting your aggressive behavior. This website is not Reddit, what is tolerated there, is not tolerated here.
