a Linux Lite 6.6 downloaded a week ago may have installed different kernel ?

[Edimion]

I thought I have kernel version 6

What makes you think this ?

As of today, an updated LL6.6 should be running kernel 5.15.0-102

Do not confuse Linux Lite version numbers with kernel version numbers.
Read the release notes for information about which kernels are on the Linux Lite ISOs.

Sincerely, I get confused when I made a profile on this forum a difficult question for newbies. That option have 6.x; 5.x; 4.x ,3.x.
Well ,I think the kernel 6 must be the one for a development version..

Yes, I forgot to read that, thanks for your answer
