sudo apt-get install gives

You might want to run apt-get -f install to correct these. The following packages have unmet dependencies: libmatroska6 Depends: libebml4 but it is not installed. Recommends : libdvdcss2 but it is not installed.

on trying apt-get -f install gives

gtk warning cannot open display at /usr/share/per15/Debconf/FrontEnd/Gnome.pm line 94, <> line 1 .

I tried dpkg-reconfigure -f results an dpkg:error:need an action option
