Creating new and bigger /boot partition

Not at all.

Even a fresh install from 6.6 LTSC takes 180MB (i try to download it yesterday but the installation aborted because of no space) and the newer 6.7 Kernels extended hardcore for around 350MB, you can see it under known issues $ solutions in Stable release Topic.

Not new info for me… i do this since 3,5 years for now… there is nothing left besides Kernel 6.1 now… take a look at my screenshot where i backup the /boot files… there is nothing else besides this one LTSC Kernel and it takes 130MB… only 70MB left, not enough room to switch Kernels.

This was maybe 3 years ago the case…
