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
What is 'referred to by another package'? Where is that package?
How to install wink?
The method using apt-get is the better than download from website.
