marking libsdl1.2debian-all for install marks ubuntu-desktop for removal

[Zachary Richey]

Marking libsdl1.2debian-all for installation(in synaptic), marks libsdl1.2debian-pulseaudio, and more importantly ubuntu-desktop for removal.

This seems like a pretty big packaging error.

This bug appears when you have ubuntu-desktop installed and attempt to install xubuntu-desktop.

Here is a copy/paste from a bug I was about to file before I found this one.

In my attempts to install Gnome, KDE and Xfce desktops, I ran into a problem with xububtu-desktop, it depends on libsdl1.2debian-alsa whereas ubuntu-desktop depends on libsdl1.2debian-pulseaudio. all of these dependencies shoudl also handle the libsdl1.2debian-all package to satisfy that dependency.

Because of this, installing xubuntu-desktop requires the removal of ubuntu-desktop.

Possible solutions:
1. ubuntu-desktop should have a dependency for libsdl1.2debian-pulseaudio | libsdl1.2debian-all preferring -pulseaudio but still being satisfied with -all

2. libsdl1.2debian-all should be marked as providing the others so that dependencies are still met.

This problem continues in Maverick Meerkat (10.10) it was not an issue in Karmic. I needed to install the all package to support esd .. I guess i can't now.
I say the option that -all satisfies all dependencies for the others makes more sense. I am pretty sure that is how it is handled before; it is sad it has appeared now.

I can also confirm this problem on 10.10 AMD64.

i had sound problems in sdlmame (maverick i386) and this faq http://sdlmame.wallyweek.org/faq/ suggested that i installed libsdl1.2debian-all and remove libsdl1.2debian-pulseaudio installed in my system by default. One month ago i did that and mame worked perfectly, but now i noticed that mame is laggy again and libsdl1.2debian-pulseaudio was reinstalled in my system probably by an update. when i try to install libsdl1.2debian-all synaptic suggests to remove ubuntu-desktop too.

Please reply if this is still an issue on a supported release.
