pull-debian-source fails use of rmadison on wily (devscripts 2.15.8ubuntu1 )

[Scott Moser]

On wily:
$ pull-debian-source hello
pull-debian-source: Error: Unable to retrieve package information from DDE: http://dde.debian.net/dde/q/udd/dist/d:debian/r:sid/p:hello/?t=json (<urlopen error [Errno -2] Name or service not known>)
pull-debian-source: Error: Unable to find hello in Debian suite "sid".

pull-debian-source silently tries to use rmadison, and then falls back to using DDE and failing with the error above. The DDE bug is bug 1453330. Fixing or replacing DDE is fine but this bug is to address the rmadison failure first.

pull-debian-source tries 'rmadison -u debian -s sid -a source hello'.

On trusty:
  $ dpkg-query --show devscripts
  devscripts 2.14.1ubuntu0.1
  $ rmadison -u debian -s sid -a source hello
   hello | 2.10-1 | sid | source

On wily:
  $ dpkg-query --show devscripts
  devscripts 2.15.8ubuntu1
  $ rmadison -u debian -s sid -a source hello
  hello | 2.10-1 | unstable | source

The rmadision usage failure is then because pull-debian-source asks for 'sid' and gets back a result with 'unstable'. It filters that result out as not a match.

Tested with python-ubuntutools from wily-proposed and `pull-debian-source` now successfully uses rmadison.

[Nish Aravamudan (nacc)]

Apologies, the version of python-ubuntutools in particular was 0.155~ubuntu3.1.

This bug was fixed in the package ubuntu-dev-tools - 0.155~ubuntu3.1

ubuntu-dev-tools (0.155~ubuntu3.1) wily-proposed; urgency=medium

  * ubuntutools/archive.py/rmadison: return results for sid if asked about
    unstable. This fixes 'pull-debian-source hello' (LP: #1508948)
