nginx is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 nginx : Depends:

 nginx-core (>= 1.4.6-1ubuntu3.2) but it is not going to be installed or
                  nginx-full (>= 1.4.6-1ubuntu3.2) but it is not going to be installed or
                  nginx-light (>= 1.4.6-1ubuntu3.2) but it is not going to be installed or
                  nginx-extras (>= 1.4.6-1ubuntu3.2) but it is not going to be installed or
                  nginx-naxsi (>= 1.4.6-1ubuntu3.2) but it is not going to be installed
         Depends: nginx-core (< 1.4.6-1ubuntu3.2.1~) but it is not going to be installed or
                  nginx-full (< 1.4.6-1ubuntu3.2.1~) but it is not going to be installed or
                  nginx-light (< 1.4.6-1ubuntu3.2.1~) but it is not going to be installed or
                  nginx-extras (< 1.4.6-1ubuntu3.2.1~) but it is not going to be installed or
                  nginx-naxsi (< 1.4.6-1ubuntu3.2.1~) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Я должен сделать склонный - получают установку-f? Что это сделало бы?
