adobe air ubuntu 12.04에 설치

Adobe Air has stopped support for Linux, so you'll be using the old version 2.6. After downloading from their website, you just change the permissions for that installer:

$sudo chmod +x AdobeAIRInstaller.bin

To install:
$sudo ./AdobeAIRInstaller.bin

An error will occur about gnome keyring, to fix this, you just have to create a symbolic link to the /usr/lib/:

$sudo ln -s /usr/lib/i386-linux-gnu/libgnome-keyring.so.0 /usr/lib/libgnome-keyring.so.0
$sudo ln -s /usr/lib/i386-linux-gnu/libgnome-keyring.so.0.2.0 /usr/lib/libgnome-keyring.so.0.2.0

Then try to install Adobe Air again, and it will work.

Note: Don't forget to remove the links you've created:

$sudo rm /usr/lib/libgnome-keyring.so.0
$sudo rm /usr/lib/libgnome-keyring.so.0.2.0

That's it!
