dpkg-reconfigure doesn't work as expected

[Scott Moser]

[Impact]

 * 'dpkg-reconfigure cloud-init' does not work as expected.

[Test Case]

 * install cloud-init
 * dpkg-reconfigure cloud-init
 * make some changes to selections
 * notice errors like:
   Use of uninitialized value in string eq at /usr/share/perl5/Debconf/Element/Multiselect.pm line 38, <GEN1> line 3.

 * notice that /etc/cloud.cfg/90_dpkg.cfg is not updated as expected.
 * running 'dpkg-reconfigure cloud-init' again will not have kept your selections.

[Regression Potential]

 * low. this was busted. the fix is correct and is in utopic.

--- original bug report ---
running 'dpkg-reconfigure cloud-init' shows an issue.

To recreate:
 dpkg-reconfigure cloud-init
 check some boxes (including anything after MAAS)
 notice that:
   * debconf complains :
      Use of uninitialized value in list assignment at /usr/share/perl5/Debconf/Element/Multiselect.pm line 12
   * /etc/cloud/cloud.cfg.d/90_dpkg.cfg does not have all datasources in it.

Also, running again will show 'Ec2' not selected.

This is blocking me from creating Trusty images for Openstack. Is there a workaround for this, and/or will the fix be backported to Trusty?

[Scott Moser (smoser)]

Danieru,
  I just uploaded this fix.
  An SRU team member will review it and release it into trusty-proposed.
  After that, it needs verification and then will et into trusty-updates.

StableReleaseProcess is described in detail at https://wiki.ubuntu.com/StableReleaseUpdates
You can help by verifying it when it *does* get into trusty-proposed.

[Chris J Arges (arges)]

Hello Scott, or anyone else affected,

Accepted cloud-init into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/cloud-init/0.7.5-0ubuntu1.1 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!
