I'm running Debian 8 on my pc. While installing file-rc package, an error occurred and the system crashed. Now the graphical interface won't show up. I tried to find a solution here, but all I got was more errors - e.g. failed to get D-Bus connection.Is there something in the file-rc installation that just breaks Debian? I'm fairly new to Linux, so it's possible that there's something obvious I'm missing. 
Unable to start Gnome after insalling file-rc
