Gnome desktop environment removed on Upgrading using synaptic

[Abhishek Verma <abhishekv@drishti-soft.com>]

Hi all,

I have Debina Unstable running on my system. I tried to upgrade the 
system using synaptic from an official debian mirror. When I looked at 
the list of packages to be removed/installed/upgraded, I found that 
gnome-desktop-environment was to be removed. I thought the new version 
might have a replacement for this, so I went ahead with the updates.

But, now my system has no desktop environment, and when I try to install 
gnome-desktop-environment, it says that it can't install since 
gnomemeeting is uninstallable. When I tried to install gnomemeeting, it 
says that it can't install because it depends on libopenh323-1.18.0 
which is uninstallable. When I tried to look for the package libopen323 
version 1.18.0, it is nowhere to be found. The current version available 
for this package is 1.15.6.

Can anybody give me some idea how should I go about installing 
gnome-desktop-environment. Also, why are there dependcies of packages 
that have not yet been put into the repository.

Thanks in advance
