Hi,

I decided upgrade my Latitude D630 to unstable from testing.

First, I have googled and having found that the good way was to set
the Pin-Priority in /etc/apt/preferences, and set /etc/apt/apt.conf to
unstable, and change sources.list, like this:

:~$ cat /etc/apt/preferences
Package: *
Pin: release a=stable
Pin-Priority: 600

Package: *
Pin: release a=testing
Pin-Priority: 650

Package: *
Pin: release a=unstable
Pin-Priority: 700
:~$
:~$ cat /etc/apt/apt.conf
APT::Default-Release "unstable";
:~$
:~$ cat /etc/apt/sources.list
(...)
deb http://ftp.br.debian.org/debian/ stable main contrib non-free
(...)
deb http://ftp.br.debian.org/debian/ testing main contrib non-free
(...)
deb http://ftp.br.debian.org/debian/ unstable main contrib non-free
(...)

I run aptitude update followed by aptitude safe-upgrade. All work very good!

When I ran  aptitude full-upgrade, nothing was done! All changes was
done when I ran safe-upgrade! Ok, I am happy here. All work very well.

On the day after, the update-manager run and tell me a lot of upgrades
packages. I simple do all changes. In my first boot after that action
the X didn't goes up.

I ran aptitude safe-upgrade and it corrected a lot of break packages.
Nautilus, foe example, was downgrade to stable version.

Why update-manager don't consider the /etc/apt/preferences?

Why update-manager work different than aptitude?

There are mistakes in my configuration? What do you suggest me to get
the latest versions of packages without hard problems?

Thank you very much!
