unattended-upgrades (Ubuntu)

Bug Description

As this is a backport of a patch that is working on maverick already a regression
test should be enough.
1. install lucid
2. install unattended-upgrades from lucid-prospoed
3. run sudo unattended-upgrades -d
4. verify that the upgrades are downloaded and installed

Binary package hint: unattended-upgrades

Accepted unattended-upgrades into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

SRU verification for Lucid:
I have reproduced the problem with unattended-upgrades 0.55ubuntu4 in lucid-updates and have verified that the version of unattended-upgrades 0.55ubuntu5 in -proposed fixes the issue.

Marking as verification-done

This bug was fixed in the package unattended-upgrades - 0.55ubuntu5

unattended-upgrades (0.55ubuntu5) lucid-proposed; urgency=low

  * unattended-upgrade:
    - backport fix for a crash when a package has no conffiles
      anymore (LP: #563912)
    - fix crash on download error (DescURI is not a valid attribute)
      LP: #591171
