Trinity desktop on Debian-Testing
 

I want to install Trinity desktop (a fork of kde3) and instructions to install it are available at: http://www.trinitydesktop.org/wiki/b...ryInstallation

However, the instructions are for Debian-Stable (and oldstable) while I am running Debian-Testing. Can I proceed with same instructions safely or will I run the risk of major problems? Thanks for your help.

I would not do so. The squeeze repo has not been updated since October 2011 and a lot have changed since then.
