I am not sure what that means. I installed using apt-get install and got the message saying I had unmet dependencies. I just assumed that the versions needed were earlier versions because of the version numbers and the fact that I do have versions of those files on my system and when i tried to download them again it stated that I had the newest versions.

As for gnopernicus I have read the following :

The problem here is that the libgail and libatk-bridge modules are not being found. You can try by
setting the LD_LIBRARY_PATH to the place where the modules are installed (lib/gtk-2.0/modules) and
also set GNOME_ACCESSIBILITY=1.

I found /usr/lib/gtk2.0/modules but am not sure how to set the path or where the file is where I should change the paths

Yasr seems to workalthough i am not sure how it functions. It reads the console screen but if I open an application it doesn't read the page. Also I have to navigate to a console as it doesn't appear to read the desktop. Iam not visually impaired myself so it is difficult to judge what is OK or not but the programs all seem a bit complicated.
