Adding Mime-type for Adobe AIR Packages on Ubuntu
If you've just put you Adobe AIR package on you server and you get something that looks like the picture below then you need to add a mime type so that apache can tell your browser what type of file it is.
The reason that apache doesn't already know about it is that the Adobe AIR format has only just been released.
To fix up a Ubuntu server all you need to do is add the following line to the /etc/mime.types file:
application/vnd.adobe.air-application-installer-package+zip air
Then restart apache with:
sudo /etc/init.d/apache restart
All done. I'm sure that the mime type will be included going forward so this won't be a problem.
thanks
