It seems that some kuki users are having questions about kernel installation.
If during installation, a question regarding the copy of the file menu.lst is asked, you have to say YES!
menu.lst needs to be upgraded so you can boot with the new kernel, you have to accept the upgrade/change or the new kernel will be installed, but you will not be able to boot into it (unless you want to manually edit the menu.lst)
To install Kuki, our kernel or kernel headers please follow our guides at: https://kuki.me/how-to/
If you still have questions after reading and trying our guides please come to our #kukilinux channel on Freenode IRC (please be patient we sleep and work too) or use our support forum kuki.me/forum
