Hi all, if i try to install wine (windows emulator for application) from the shell bu typing the command "sudo apt-get install wine" , it give me that error : ubuntu@udoo:~$ sudo apt-get install wine Reading package lists... Done Building dependency tree Reading state information... Done Package wine 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 'wine' has no installation candidate can anyone help me, please??
