apt-get: fix deps after a dist-upgrade with ppa:gnome3-team/gnome3

[Daniele Guerrieri]

Hi,

I've tried to install gnome3 in the following way:
1)add-apt-repository ppa:gnome3-team/gnome3
2)apt-get update
3)apt-get upgrade
4)apt-get dist-upgrade # (Is this wrong?)

It didn't work well. So i tried to remove it, with
#$ ppa-purge ppa:gnome3-team/gnome3

I hoped to rescue the situation as it were before adding gnome3 ppa, but
ppa-purge didn't work too: i had to repeat add-apt-repo for gnome3 and
repeat ppa-purge gnome3, after many many apt-get install -f and apt-get
update, and a lot of help from aptitude (examine and '!').

I also had to remove some pkgs by hand to resolve conflicts between the new
.3 version and the old 2.32 which i was trying to reinstall (automagically
with ppa-purge, which didn't work).

To obtain a working GNOME 2.32 environment, therefore i had to install
several gnome packages by hand, for example banshee, totem, evince and also
gnome-panel! why an "important" pkg such as gnome-panel hasn't been
installed as a dep?

Is there an option to fix all "important" deps, which isn't apt-get -f ? or
a meta package which holds all GNOME packages (maybe
gnome-desktop-environment)?
How can i revert a wrong dist-upgrade?

Another thing that i cannot understand: why has the boot splash image
changed? now i have a blue debian img.. where is the ubuntu splash image,
maybe in grub2-splashimages?

Thank you!
Daniele
