E: Package 'libapache2-mod-fastcgi' has no installation candidate --- Debian Server

That package is in the non-free, but your sources list looks wrong, you've got multiple sources on the same line and 'hxxp' instead of 'http'. With that as your sources.list you will get errors with apt-get update (which should indicate your problem).

Create the /etc/apt/sources.list file with just the following:

deb http://ftp.es.debian.org/debian stable main contrib non-free
deb-src http://ftp.es.debian.org/debian stable main contrib non-free

deb http://ftp.debian.org/debian/ wheezy-updates main contrib non-free
deb-src http://ftp.debian.org/debian/ wheezy-updates main contrib non-free

deb http://security.debian.org/ wheezy/updates main contrib non-free
deb-src http://security.debian.org/ wheezy/updates main contrib non-free

Re-run 'apt-get update' and then you should be able to install with 'apt-get install libapache2-mod-fastcgi'
