I'm getting the following.
I will have some time tomorrow night to try again.
Fresh install of Debian 7 no extras
root@debian:/home/john# apt-get install desktop-base-trinity kde-trinity
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
kde-trinity : Depends: tde-trinity but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
My sources list
deb
http://mirror.xcer.cz/trinity-sb wheezy deps-r14 main-r14
deb
http://ftp.us.debian.org/debian stable main contrib non-free
deb
http://ftp.debian.org/debian/ wheezy-updates main contrib non-free
deb
http://security.debian.org/ wheezy/updates main contrib non-free
You can use:
apt-get install desktop-base-trinity tde-trinity
Package kde-trinity is only transitional package.
I'll solve conflict with his dependencies later.
