First, I want to share some bad news. Adobe no longer supports Adobe Air for Linux. You can get further explanation from Adobe from this post. Adobe will not provide any updates including security updates for Adobe Air. You could still install the latest version of Adobe Air (which is version 2.6) from the archive provided that the air applications you are running still supports Adobe Air version 2.6.
Here is my suggestions. If you can live without Adobe Air and its apps, please do not install Adobe Air for Linux. I am more concern about not getting any security updates rather than features update. Please search for other alternatives. For TweetDeck user, you can install the Chrome version of TweetDeck instead of desktop version.
If you still need Adobe Air and its apps, you can follow the instructions below. I've installed Adobe Air for Linux (v2.6) and tested some air applications with it. It works fine for now. As I've mentioned earlier, I'm more concern about not getting security updates, please note that you'll be installing at your own risk.
Getting Adobe Air for Linux (v. 2.6)
To get the last version of Adobe Air, visit the Adobe Archive page. Scroll down to "Adobe Air 2.6 runtime downloads" and download the bin file labeled "Adobe Air 2.6.0 Linux (15.4MB)". You will be downloading a file named "AdobeAIRInstaller.bin"
Before you runs the bin file, you need to install all the essential libraries (both 32-bit and 64-bit) required. Use the following command:
$sudo yum install -y ld-linux.so.2 gtk2-devel.i686 libdbus-glib-1.so.2 libhal.so.1 rpm-devel.i686 libXt.so.6 gnome-keyring-devel.i686 libDCOP.so.4 libxml2-devel.i686 nss-devel.i686 libxslt.i686 xterm rpm-build libgnome-keyring.i686
Install Adobe Air
To install the Adobe Air, navigate to where you kept the file "AdoebAIRInstaller.bin" and use the command:
$chmod +x AdobeAIRInstaller.bin
Install AIR Apps
I've successfully installed twhirl, TweetDeck (desktop version) and Zinio Reader 4. All applications installed successfully, although it took a while to install on my virtual machine. If you encounter any problem installing TweetDeck (desktop version), don't bother to troubleshoot it, switch to TweetDeck for Chrome version.
