Trying to upgrade my Ubuntu 12.04 vps I get the following error:

henrik@neung:~$ sudo apt-get upgrade
[sudo] password for henrik: 
Reading package lists... Done
Building dependency tree

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 nginx-full : Depends: nginx-common (= 1.2.4-1ubuntu0ppa2~precise) but 1.2.4-2ubuntu0ppa1~precise is installed
E: Unmet dependencies. Try using -f.

So I try to run this:

henrik@neung:~$ sudo apt-get -f install

    Take your time looking this general purpose question. If you have no luck with that, try reinstalling the nginx package: sudo apt-get remove nginx* && sudo apt-get install nginx-full

    I went through the whole thing, but no luck. So I tried removing and installing, and after a reboot everything worked ok. Could you post this as an answer so I can accept it as the right solution.

The problem is that nginx-full depends on nginx-common, this means that you can't install the package nginx-full without have a specific version of nginx-common.

Here is an question dedicated to this problem, but the resolution is very extensive, reaching to, not only one, but different cases. So I will show you a short but effective method.

Actually, I don't know how to install that version of nginx-common, but I know that you will solve your problem by reinstalling all the package. To do that you must enter the following command in a terminal.

sudo apt-get remove nginx* && sudo apt-get install nginx-full

    a reboot was required after these steps to make it all work! Thanks

    I needed to stop Apache (also serving on port 80) before this worked. Commented Sep 22, 2015 at 3:39

I had the same problem. I DO NOT have Apache, and nothing else was blocking my port 80. I could NOT install nginx with

sudo apt-get install nginx

nor with

sudo apt-get install nginx-common nginx-full

After one week I stumbled over this little blog: https://etc.banana.fish/?p=75

In this blog, the solution is:

  1. Install nginx-common: sudo apt-get install nginx-common
  2. Remove listen [::]:80 default_server; from /etc/nginx/sites-enabled/default (I made this using the root-user)
  3. Just to be sure, I did reboot my server.
  4. Just to be sure twice, I did sudo apt-get update and then sudo apt-get upgrade.
  5. Now I finally called sudo apt-get install nginx-full and it worked!

Afterwords I could see the Titlescreen of nginx, when I typed in the IP of my remote server!

I have a strong feeling that you forgot to run sudo apt-get update prior to running sudo apt-get upgrade - the package manager uses old information about nginx-common package version while nginx-full requires a newer version.

    No, I did that.
