"ubuntu-cloudimg-query xenial daily" fails with "confused by argument: xenial"

[Martin Pitt]

I'm investigating why LXC's tests [1] have started failing so often with

   ubuntu-cloudimg-query is /usr/bin/ubuntu-cloudimg-query
   wget is /usr/bin/wget
   confused by argument: xenial
   There is no download available for release=xenial, stream=daily, arch=amd64

http://autopkgtest.ubuntu.com/packages/l/lxc/xenial/amd64/

Indeed this seems to be some weird glitch in ubuntu-cloudimg-query that curiously only seems to happen in the data center. I pretty much ruled out proxy settings, as that works fine for other releases and I tried unsetting proxy vars too:

$ rm -rf ~/.cache/ubuntu-cloudimg-query/; ubuntu-cloudimg-query precise --format '%{url}\n'; echo $?
https://cloud-images.ubuntu.com/server/releases/precise/release-20160315/ubuntu-12.04-server-cloudimg-amd64.tar.gz
0

$ rm -rf ~/.cache/ubuntu-cloudimg-query/; ubuntu-cloudimg-query trusty daily --format '%{url}\n'; echo $?
https://cloud-images.ubuntu.com/server/trusty/20160411/trusty-server-cloudimg-amd64.tar.gz
0

$ rm -rf ~/.cache/ubuntu-cloudimg-query/; ubuntu-cloudimg-query xenial daily --format '%{url}\n'; echo $?
confused by argument: xenial
1

strace shows that for the latter case, u-c-q immediately exits after "confused by argument: xenial", so I suspect it's some weird bug in argument parsing.

So I think this needs to be fixed in the lxc package. Either add "Restrictions: needs-recommends" or add "distro-info" as a test dependency.

[Launchpad Janitor (janitor)]

This bug was fixed in the package lxc - 2.0.0-0ubuntu2

---------------
lxc (2.0.0-0ubuntu2) xenial; urgency=medium

  * Add a distro-info test dependency as it's needed to get information
    about new Ubuntu releases. (LP: #1572188)

    This is needed to fix the current autopkgtest failures.
