After much searching, I struggled to find the information I required in regards to a fix for the 'error resolving dependencies' problem. Most of the information revolves around 'VLC Player'. I am not attempting to install this program (for the moment). I was attempting to test the efficiency and quality of some of the programs, for example 'GNOME Desktop Environment'. This is where I came across problems. I received the following message... 'Error resolving dependencies Unable to resolve dependencies for some packages selected for this installation. Details -> notification-daemon-xfce conflicts with notify-daemon Missing Dependency: gecko-libs = 1.8.1.8 is needed by package yelp' As I sifted through the mass of programs available, (and attempted to install a few in the mean time), I realised that the same problem continued to exist, only through different details. For example, if I attempted to download a gaming program, I would receive a message of the same nature with different details about a missing file or dependencies. Is it possible that there is a conflict in installation? Will the use of a system recovery be required? Is there a solution for this problem? I have no problems in accessing the terminal and, provided I have instructions, I can complete most instructions. I have tried numerous solutions, all with no success. What can I do? Kind regards, Ian
