nginx is already the newest version.
nginx set to manually installed.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
nginx : Depends: nginx-core (>= 1.4.6-1ubuntu3.1) but it is not going to be installed or
nginx-full (>= 1.4.6-1ubuntu3.1) but it is not going to be installed or
nginx-light (>= 1.4.6-1ubuntu3.1) but it is not going to be installed or
nginx-extras (>= 1.4.6-1ubuntu3.1) but it is not going to be installed or
nginx-naxsi (>= 1.4.6-1ubuntu3.1) but it is not going to be installed
Depends: nginx-core (< 1.4.6-1ubuntu3.1.1~) but it is not going to be installed or
nginx-full (< 1.4.6-1ubuntu3.1.1~) but it is not going to be installed or
nginx-light (< 1.4.6-1ubuntu3.1.1~) but it is not going to be installed or
nginx-extras (< 1.4.6-1ubuntu3.1.1~) but it is not going to be installed or
nginx-naxsi (< 1.4.6-1ubuntu3.1.1~) but it is not going to be installed
nginx-full-dbg : Depends: nginx-full (= 1.4.6-1ubuntu3.1) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
