Bug#1002605: `apt-get source calendar' downloads the wrong package

[Stéphane Glondu <glondu@debian.org>]

Package: apt
Version: 2.3.13
Severity: important

Dear Maintainer,

`apt-get source calendar' downloads the bsdmainutils source package
instead of calendar. I suspect this is because bsdmainutils is the
source package of the calendar binary package.

I think `apt-get source $FOO' should try to download $FOO if $FOO
exists as a source package, and only after fallback to downloading the
source package of $FOO if it exists only as a binary package.


Cheers,

-- 
Stéphane
