Ubuntu has two kernels in /boot

Question

my server running Ubuntu 12.04.4 LTS has two kernel images in /boot at the moment 3.11.0-19 and 3.2.0-60
And every time i do a dist-upgrade the both get updated.
Is this necessary or how can i remove the "oldest" one?

as Nux said i've removed older kernels. now it shows:

dpkg --list | grep linux-image
linux-image-3.11.0-20-generic 3.11.0-20.34~precise1
Linux kernel image for version 3.11.0 on 64 bit x86 SMP
linux-image-3.2.0-54-generic 3.2.0-54.82
Linux kernel image for version 3.2.0 on 64 bit x86 SMP
linux-image-generic-lts-saucy 3.11.0.20.18
Generic Linux kernel image

and uname -r still says 3.2.0-54 why not 3.11.0-20 ?

It is good practice to keep at least one working ("old") kernel in /boot. Otherwise, if a new kernel displays issues (which might even be Linux not booting at all), the repair procedure gets unnecessarily complicated.

it's not old kernels as in grub boot loader. it's just 2 separate kernels. not sequential.
uname -r gives 3.2.0-54
which makes it even stranger to me! – Nijboer IT May 02 '14 at 08:51
you can follow that answer and remove the old kernel – nux May 02 '14 at 08:54
which should i remove than? everything older than 3.2.0-54? or older than 3.2.0-60 or older than 3.11.0-19? – Nijboer IT May 02 '14 at 08:55
older than 3.2.0-54 – nux May 02 '14 at 08:58
i've updated the question. with feedback – Nijboer IT May 02 '14 at 09:08
Okey Solved.. this is one of the reasons to reboot a linux distro! now uname -r shows the correct value.. thanks! – Nijboer IT May 02 '14 at 09:33
