"hwe-support-status --show-all-unsupported" fails

[frankster]

TEST CASE:
1. install 12.04
2. apt-get install linux-image-generic-lts-saucy
3. install update-manager-core from precise-updates
4. run hwe-support-status --show-all-unsupported
5. verify it crashes
6. install update-manager-core from precise-proposed
7. repeat step 4
8. verify that it works this time.

Expected behaviour:
"hwe-support-status --show-all-unsupported" lists any unsupported HWE packages

Actual behaviour:
hwe-support-status crashes with the following stack:

Traceback (most recent call last):
  File "/usr/bin/hwe-support-status", line 235, in <module>
    print(twrap(" ".join(unsupported_hwe_packages)))
TypeError: sequence item 0: expected string, instance found

Could you take a look at this Michael?

Just want to add that I installed using the vanilla Ubuntu Server 12.04 download image and this bug affects me.

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/1:0.156.14.16 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 working on verification, looks good so far, but in an overabundance of caution I'm testing with all available HWE stacks .................. and just noticed that I should actually combine with SRU testing for bug #1342424 ................. so this is really just a note to myself.

[Erick Brunzell (lbsolost)]

Looks good so changed to verification-done. I tested with all available HWE stacks.

[Chris J Arges (arges)]

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.

[Launchpad Janitor (janitor)]

This bug was fixed in the package update-manager - 1:0.156.14.16

---------------
update-manager (1:0.156.14.16) precise-proposed; urgency=low

  * HweSupportStatus/consts.py:
    - use ISO date format instead of the locales date format because
      pam_motd does not set the LANG environment (LP: #1342424)
  * hwe-support-status:
    - fix crash with hwe-support-status --show-all-unsupported,
      thanks to "frankster" (LP: #1341324)

Is it possible someone could take a look at bug #1341320?

[Brian Murray (brian-murray)]

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