HWE meta packages "linux-signed-generic"/"linux-signed-image-generic" not considered

[Michael Vogt]

[Impact]
 * Users with the linux-signed-image-lts-$VER kernel do not get the correct hwe-support-status output

[Test Case]
 * install 12.04 (any version) server
 * install linux-signed-image-generic-lts-saucy
 * run hwe-support-status
 * verify that you get a prompt with a line that contain "apt-get install" but no package to install
 * install the updated version
 * verify that that you get a message that advices to upgrade to linux-signed-image-generic-lts-trusty

[Regression Potential]
 * Little

Hello Michael, or anyone else affected,

Accepted update-manager into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/update-manager/1:0.156.14.18 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

I'm verifying that it works for Precise.

Steps I did:
I downloaded http://releases.ubuntu.com/12.04/ubuntu-12.04.4-desktop-amd64.iso. This has linux-signed-generic-lts-saucy installed.
I updated to the latest update-manager version in -updates:
# apt-get update
# apt-get install update-manager update-manage-core
# dpkg-query -W update-manager
update-manager 1:0.156.14.17

I verified that `hwe-support-status --show-replacements` doesn't show the signed kernel:
# hwe-support-status --show-replacements
linux-generic-lts-trusty libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty linux-image-generic-lts-trusty

Then I enabled precise-proposed, and installed update-manager 1:0.156.14.18, the one being SRU'ed here. At that point, --show-replacements showed the signed kernel:
# hwe-support-status --show-replacements
linux-generic-lts-trusty libgl1-mesa-glx-lts-trusty linux-image-generic-lts-trusty linux-signed-generic-lts-trusty linux-signed-image-generic-lts-trusty xserver-xorg-lts-trusty

[Alkis Georgopoulos (alkisg)]

Some additional information:
If I remove the update-manager package, then hwe-support-status 1:0.156.14.18 gives an apt-get line without requiring the "--show-replacements" parameter. The exact output is:

Your current Hardware Enablement Stack (HWE) is no longer supported
since 2014-08-07. Security updates for critical parts (kernel
and graphics stack) of your system are no longer available.
For more information, please see:
http://wiki.ubuntu.com/1204_HWE_EOL
To upgrade to a supported (or longer supported) configuration:
* Upgrade from Ubuntu 12.04 LTS to Ubuntu 14.04 LTS by running:
sudo do-release-upgrade
OR
* Install a newer HWE version by running:
sudo apt-get install linux-generic-lts-trusty libgl1-mesa-glx-lts-trusty linux-image-generic-lts-trusty linux-signed-generic-lts-trusty linux-signed-image-generic-lts-trusty xserver-xorg-lts-trusty
and reboot your system.

...while with 1:0.156.14.17 it doesn't mention the signed packages:
* Install a newer HWE version by running:
sudo apt-get install linux-generic-lts-trusty libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty linux-image-generic-lts-trusty

I too verify that 1:0.156.14.18 in precise-proposed fixes the issue.

With update-manager 1:0.156.14.17 the exact output of the "hwe-support-status --show-replacements" is:

administrator@server:~$ hwe-support-status --show-replacements
linux-generic-lts-trusty libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty linux-image-generic-lts-trusty

and after upgrading update-manager to 1:0.156.14.18 the output is:

administrator@server:~$ hwe-support-status --show-replacements
linux-generic-lts-trusty libgl1-mesa-glx-lts-trusty linux-image-generic-lts-trusty linux-signed-generic-lts-trusty linux-signed-image-generic-lts-trusty xserver-xorg-lts-trusty

Also, as mentioned by Alkis Georgopoulos at the above comment after removing the update-manager package the exact output of the command "hwe-support-status" 1:0.156.14.17 gives an apt-get line without requiring the "--show-replacements" and without mentioning the signed packages.

administrator@server:~$ hwe-support-status
