Comment 26 for bug 508545

Wesley, as you can see from my comment #23 I already have a pinning preferences file. And the correct values are picked up whether the file is named /etc/apt/preferences or /etc/apt/preferences.d/preferences. Therefore, as far as I am concerned the issue does not exist.

How about you run the following cadence instead with the old aptitude package installed?

+--[ /etc/apt/preferences.d/lp508545 ]
|
| Package: *
| Pin: release a=lucid-proposed
| Pin-Priority: 99
|
+--

Then, show us the output of "apt-cache policy aptitude". For me, that snippet works in BOTH locations, i.e. no bug.
