HWE support LTS

[paul.a]

Server Ubuntu 14.04.5 LTS (GNU/Linux 3.19.0-25-generic x86_64) (full apt update and upgrade except distro) showed on reboot:

WARNING: Security updates for your current Hardware Enablement Stack
ended on 2016-08-04:
* http://wiki.ubuntu.com/1404_HWE_EOL

but the wiki page shows support until April 2019 with the Xenial 4.4 kernel, so as per wiki:

sudo apt-get install --install-recommends linux-generic-lts-xenial

Done... but inxi -Fx still showing after reboot:

System: Host: server4 Kernel: 3.19.0-25-generic x86_64 (64 bit, gcc: 4.8.2) Console: tty 0 Distro: Ubuntu 14.04 trusty

Any thoughts or suggestions, please
Note: all my other servers are 16.04, but I just need this one for legacy MySQL 5.5 reasons.
Thanks -- paul

* You are affected if it shows a kernel with the following version: 3.16 or 3.19 or 4.2
* You are not affected if it shows a kernel with the following version: 3.13 or 4.4

This method does not check for a HWE graphics stack. However, you cannot get a HWE graphics stack without a corresponding HWE kernel unless you've done things manually. Note that such a combination (HWE graphics with non-HWE kernel) is not supported.

hwe-support-status --show-all-unsupported

Upgrading the kernel shouldn't change much for you unless you are using the AMD and fglrx drivers

So there will be no more updates to the 3.19 kernel as 15.04 is EOL (No longer supported)

So to upgrade the kernel I usually run this:

sudo apt-get install linux-image-generic-lts-xenial linux-generic-lts-xenial

Or:

sudo apt-get install linux-signed-generic-lts-xenial linux-signed-image-generic-lts-xenial

Thank you for replying. I have tried your suggestions, which are variants of what I had already tried, but this server (14.04.5 LTS) still uses "uname -r 3.19.0-25-generic". Maybe I've traced this to grub.

The "upgrade" to a Xenial-based 4.4 kernel does install it to /boot but gives the following:

/.../
Replacing config file /run/grub/menu.lst with new version

But the write to grub is failing (ignored, whatever):

cat: /run/grub/menu.lst: No such file or directory

I'm guessing this is a bug, there is no mention of grub in syslog or boot.log -- on a desktop you might see grub, on a rack-mount server through ssh it's invisible.
Again thanks -- paul
