After an update of my Ubuntu I came to the error, "I cannot update since /boot is full". The thing is, that when I compared the results of the two following commands $dpkg --list 'linux-image*', $uname -r I noticed that I use an older kernel. In my case the second command gave 3.13.0-24-generic and the first gave many newer version kernels e.g. linux-image-3.13.0-46-generic. The question is 1.why Grub does not update to a new kernel version? 2.I am not sure which kernel versions to delete in order to free some space in /boot. The question here My /boot partition hit 100% and now I can't upgrade. Can't remove old kernels to make room answers how to free some space but not why my Grub does not use the newer kernel vesrions.
