Two 14.04.2 LTS installations, different kernel versions?

Question

I have two installations of Ubuntu server 14.04.2 LTS, both installed from the same media (I just checked - the DVD used for both is still on the drive of one of them), but a couple of months apart. All packages appear to be up to date, but see the kernel version on one is higher than that on the other:

root@bud:~$ uname -r
3.13.0-55-generic

root@mud:~$ uname -r
3.16.0-40-generic

Why is this? Shouldn't I be running the 3.16 kernel on the first one?

They have been installed not from same media )) First from 14.04.1 or 14.04, second from 14.04.2. — Pilot6, Jun 16 '15 at 21:02
I see, but /etc/issue says Ubuntu 14.04.2 LTS for both of them. How do get the same kernel version for both? — TommyPeanuts, Jun 16 '15 at 21:03
possible duplicate of kernel version 3.13 even I have ubuntu 14.04.2 — Pilot6, Jun 16 '15 at 21:06
Not quite a duplicate since this isn't the result of an upgrade, but almost :-) — TommyPeanuts, Jun 17 '15 at 11:51

Short answer is run

sudo apt-get install linux-generic-lts-utopic

on the first one.

But 3.13 will be supported till 14.04 EOL. For a server maybe it is better to keep it.

Or maybe it is time to run

sudo apt-get install linux-generic-lts-vivid

on both to get 3.19.

14.04.3 will come with 3.19 in about a month and support of 3.16 will come to an end a bit later.
