unattended-upgrade crashed with AttributeError in main()

[Muelli]

TEST CASE:
1. install lucid
2. run sudo apt-get update
3. run sudo ifconfig eth0 down (or wlan0 down if on wlan)
4. run sudo unattended-upgrades
5. verify that it fails and errors with "AttributeError: 'apt_pkg.AcquireItem' object has no attribute 'DescURI'
"
6. install unattended-upgrades from lucid-proposed (reenable network first ;)
7. repreat step 4 and verify that it gives a proper error message now

Binary package hint: unattended-upgrades

I didn't do anything myself really. It automatically went off to fetch updates, I guess.

It seem like when it attempt to run there is no network connection or the source is not available.

I can reproduce the problem if there is no network.

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!

Sorry I can't test, I'm now on Ubuntu 10.10!

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
