remove unsupported packages after receiving HWE warning

said76 · 08-28-2016, 07:51 PM

Hi,

I've been running Ubuntu Server 14.04 LTS all along and it's going well until recently I received the following message whenever I logged in:

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

To upgrade to a supported (or longer-supported) configuration:

* Upgrade from Ubuntu 14.04 LTS to Ubuntu 16.04 LTS by running:
sudo do-release-upgrade

OR

* Switch to the current security-supported stack by running:
sudo apt-get install linux-signed-image-generic-lts-xenial linux-signed-generic-lts-xenial

and reboot your system.

========== END of MESSAGE ============

I went to check my system status, it gave the following:
You have 47 packages (4.8%) supported until May 2017 (9m)
You have 3 packages (0.3%) supported until May 2017 (3y)
You have 695 packages (70.4%) supported until May 2019 (5y)
You have 114 packages (11.6%) supported until February 2015 (9m)

You have 10 packages (1.0%) that can not/no-longer be downloaded
You have 118 packages (12.0%) that are unsupported

Your Hardware Enablement Stack (HWE) is supported until April 2019.

So I don't quite understand why it prompted me for the upgrade.

Anyhow, I gave in and run the command below as instructed by the message:
sudo apt-get install linux-signed-image-generic-lts-xenial linux-signed-generic-lts-xenial

and rebooted it.

Then, I logged in and got the following:
The following packages are no longer supported:
linux-signed-generic-lts-utopic linux-image-3.16.0-52-generic linux-image-3.16.0-30-generic linux-image-extra-3.16.0-30-generic linux-image-3.16.0-69-generic linux-image-extra-3.16.0-55-generic linux-image-3.16.0-59-generic linux-image-extra-3.16.0-48-generic linux-image-extra-3.16.0-53-generic linux-image-extra-3.16.0-46-generic linux-image-3.16.0-60-generic linux-image-3.16.0-71-generic linux-image-extra-3.16.0-67-generic linux-image-extra-3.16.0-77-generic linux-image-3.16.0-48-generic linux-image-extra-3.16.0-52-generic linux-image-extra-3.16.0-69-generic linux-image-extra-3.16.0-50-generic linux-image-extra-3.16.0-70-generic linux-image-extra-3.16.0-60-generic linux-image-extra-3.16.0-59-generic linux-image-3.16.0-70-generic linux-image-3.16.0-57-generic linux-image-extra-3.16.0-62-generic linux-image-extra-3.16.0-49-generic linux-image-3.16.0-50-generic linux-image-3.16.0-73-generic linux-image-3.16.0-55-generic linux-image-3.16.0-62-generic linux-image-3.16.0-67-generic linux-image-extra-3.16.0-73-generic linux-image-extra-3.16.0-76-generic linux-image-extra-3.16.0-71-generic linux-image-3.16.0-76-generic linux-image-3.16.0-49-generic linux-image-3.16.0-77-generic linux-image-3.16.0-53-generic linux-image-3.16.0-46-generic linux-headers-generic-lts-utopic linux-signed-image-generic-lts-utopic linux-image-extra-3.16.0-57-generic

Please upgrade them to a supported HWE stack or remove them if you
no longer need them.

I'm wondering how I'd remove the items from the list above.

Here is the detail of my system:
Linux UbuntuServer 3.16.0-77-generic #99~14.04.1-Ubuntu SMP Tue Jun 28 19:17:10 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Thank you in advance

It's because you installed Ubuntu 14.04.2 and support for the kernel it came with has ended (the 3.16.x one backported from Ubuntu 14.10)

and rebooted it.

If "uname -a" is still telling you that you're running the 3.16 kernel, then you need to bring up the grub menu and boot into the xenial/4.4.x kernel.

Again, you need to first make sure you're booted into the 4.4.x kernel. After that I'd guess this would do it:

Code:

sudo apt-get autoremove

Or, you could just copy the list and paste it after 'apt-get remove' (there will probably be some line breaks to remove).

You can run:
ubuntu-support-status

Which will give you output like this:

You have 4 packages (0.5%) supported until February 2018 (9m)
You have 641 packages (88.0%) supported until May 2019 (5y)

You have 2 packages (0.3%) that can not/no-longer be downloaded
You have 81 packages (11.1%) that are unsupported

You can also run this to get the list of unsupported:
ubuntu-support-status --show-unsupported
