I tried installing fbreader, following all the steps, but ended up with unmet dependencies, i also think a file is referenced in two locations at once and hence killing it..

any ideas how I can fix it? i've done alot of research and tried:

sorry for the formatting, but it basically isn't liking:

Any ideas? Also I don't care about keeping the program, but the error is stopping

sudo apt-get remove fbreader

from working too.
