Actually looking at the kernel version, that is a Debian style version, it is just totally obsolete.

Make sure you have the package 'linux-image-amd64' installed, which will
keep your kernel at the current debian version whenever you do a proper
upgrade.  Note a proper upgrade is apt-get dist-upgrade (not apt-get
update) or apt full-upgrade (probably preferred these days over apt-get).

upgrade only upgrades package versions, but won't install any new
package names, while dist-upgrade/full-upgrade will allow new packages
to be installed, and since a new kernel version has a new package name
(since the version is in the name) you need the full upgrade in order
to get a kernel upgrade.  upgrade is only valid within a release to get
point release updates and security fixes.  To go to another release,
or in fact anytime when running testing or unstable where things change
a lot, the full upgrade is often required.
