Bug#152129: -t ignoring also happens with binary installs and upgrades

[Cameron Stone <camerons@cse.unsw.edu.au>]

My sources.list contains entries for stable, testing, and unstable. I'm 
currently tracking testing (with a few unstables). I have a 
'APT::Default-Release "testing";' line in my apt.conf.

When I run apt-get install on a package I know has an upgrade, or 
apt-get upgrade (or dist-upgrade or dselect-upgrade) with no options apt 
tries to downgrade the package (or packages) to stable. This also 
happens if I include a '-t testing' or '-t unstable'. This is similar to 
this bug which is why I'm mailing you.

However, as an added twist, if you specify '-t stable' it installs the 
testing release. This works for both install and the upgrade commands.

Using apt-get install package/release *does* work correctly, but you 
can't do that on an apt-get upgrade.

This happens with apt versions 0.5.28.4 and 0.5.28.1 (the unstable and 
testing releases).

Thanks,
	Cameron.

It is much easier to do and die than it is to reason why.
