empty apt-get install command suggested by hwe-support-status

[frankster]

[Impact]
 * Users who have leftover components of a HWE stack get a misleading message in /etc/motd

[Test Case]
 * install 12.04 (any version) server
 * install xserver-xorg-video-sis-lts-saucy (or any random -lts-saucy non-meta package)
 * run hwe-support-status
 * verify that you get a message that contains:
"""Install a newer HWE version by running:
sudo apt-get install
"""
 * install the updated version
 * verify that you get a message with "The following packages are no longer supported:" and no longer a empty apt-get install message.

[Regression Potential]
 * Little, it could report too much to remove but thats very unlikely.

---------------
hwe-support-status generates an empty apt-get command as can be seen in its output appended below. As the command doesn't really make sense I assume that this is not the expected behaviour.

Status changed to 'Confirmed' because the bug affects multiple users.

[Paul Pace (openletter)]

I have a 2-week old install of Precise and I get this issue, although only 1 of 3 of my servers has this bug.

[Stephen Michael Kellat (skellat)]

This is not a bug. There is no 12.04.5 release of Mythbuntu. If you need additional hardware enablement you need to upgrade to 14.04. Please consult the release announcement here for a listing of flavors that are actually participating in 12.04.5: https://lists.ubuntu.com/archives/ubuntu-announce/2014-August/000189.html

Displaying misleading and erroneous text is clearly a bug:

----------------------------
* Install a newer HWE version by running:
sudo apt-get install

[Paul Pace (openletter)]

I am running vanilla Ubuntu Server 12.04 and I am experiencing this bug.

I have to say, if the new Ubuntu LTS plan is to require upgrading the distribution before its scheduled support expiration, that's disappointing.

Hello frankster, 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!

[Alkis Georgopoulos (alkisg)]

Verifying for precise.
I fully updated all the meta packages. And I also removed all the old meta packages.
I only kept a couple of old kernels around.
Then, the previous update-manager-core version produced an empty apt line,
while the newer one didn't.

Exact output:

# dpkg-query -W update-manager-core
update-manager-core 1:0.156.14.17

The verification of the Stable Release Update for update-manager has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

[Brian Murray (brian-murray)]

I've forward ported the HWE support status code to Yakkety, so I'm setting this to Fix Released.
