Bug#685136: cannot override /etc/apt/preferences in /etc/apt/preferences.d/myfile

[Harald Dunkel <harald.dunkel@aixigo.de>]

Package: apt
Version: 0.8.10.3+squeeze1

Seems that I cannot override the pinning defined
in /etc/apt/preferences by a local config file in
/etc/apt/preferences.d. Sample:


/etc/apt/preferences:

	Package: *
	Pin: release a=squeeze-backports
	Pin-Priority: 200


/etc/apt/preferences.d/local

	Package: *
	Pin: release a=squeeze-backports
	Pin-Priority: 500


According to the man page the next run of

	apt-get update
	apt-get install git

would install the git from debian-backports, since I
did not set a target release, 500 == 500, and the
version number of git in debian-backports is higher
than Squeeze's git. But it doesn't.

If I set the 500 in /etc/apt/preferences

	Package: *
	Pin: release a=squeeze-backports
	Pin-Priority: 500

then it works, i.e. overriding the Pin-Priority is
somehow flawed.

This is surely not what one would expect. It took me
quite some time to figure out. Would it be possible
to fix this?


Many thanx
