So while running sudo apt-get -y upgrade is usually reasonable, the -y flag should rarely be used with dist-upgrade. The reason you don't get new kernel versions with sudo apt-get upgrade is because they each are provided by separate, differently named packages. The kernel version is part off the name. This is to facilitate keeping an old kernel installed alongside a newer kernel and being able to select between them in the GRUB menu. The automatic offering of new kernel packages for installation is accomplished by having a metapackage like linux-image-generic installed.
