How to install wink?

Question

I can't install wink by the following commands:

  sudo apt-get install wink

Here is the log

  sam@sam:~$ sudo apt-get install wink
  [sudo] password for sam: 
  Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  Package wink is not available, but is referred to by another package.
  This may mean that the package is missing, has been obsoleted, or
  is only available from another source

  E: Package 'wink' has no installation candidate

1. What is 'referred to by another package'? Where is that package?

2. How to install wink?

The method using apt-get is the better than download from website.

Thank you~

1. Wink Package Search, This mean that the package is missing..

2. You have two option :

   • Find someone that have a PPA here for your Ubuntu version. Search for wink package there..
   • Compiling from source.
