indicates a package origin of Ubuntu for Ubuntu systems

[Brian Murray]

bug 1014269 is an example of a bug reported from an Ubuntu system where a lot of the dependencies are lists as [origin: Ubuntu] which doesn't make a lot of sense.

I believe this can happen when the cache doesn't have a record for the origin of the package. I was able to test this by changing which mirror I use with software-properties-gtk and not updating my sources e.g. no apt-get update was run.

In [1]: from apport.packaging_impl import impl as packaging
In [2]: packaging.is_distro_package('apt-clone')
Out[2]: False
In [3]: pkg = packaging._apt_pkg('apt-clone')
In [4]: pkg.candidate.origins
Out[4]: [<Origin component:'' archive:'now' origin:'' label:'' site:'' isTrusted:False>]

It is interesting that bug 1014269 is about ubiquity and from a Live CD. I'd expect a lot of bugs reported from Live CDs to be in this situation. This is rather important now that the error tracker is taking into account package origins.

Actually, my test doesn't make that much sense as:

In [9]: packaging.get_package_origin('apt-clone')

returns None
