Download http://airdownload.adobe.com/air/lin/download/2.6/AdobeAIRInstaller.bin
Make the .bin file executable
$ chmod a+x AdobeAIRInstaller.bin
Run the .bin file by executing following
$ ./AdobeAIRInstaller.bin
If you get a permission error and/or you're dealing with an installer that applies system-wide changes you might have to launch your application with root privileges
$ sudo ./AdobeAIRInstaller.bin
If you get error like /tmp/air.oinYTZ/setup: error while loading shared libraries: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory, then running following commands
Install i386 libraries, that are required for successful installation and running of Adobe Air and air applications
$ sudo apt-get install libxt6:i386 libnspr4-0d:i386 libgtk2.0-0:i386 libstdc++6:i386 libnss3-1d:i386 lib32nss-mdns libxml2:i386 libxslt1.1:i386 libcanberra-gtk-module:i386 gtk2-engines-murrine:i386
Install libgnome-keyring0:i386 package.
$ sudo apt-get install libgnome-keyring0:i386
Create symlinks to gnome-keyring so Adobe Air could see it.
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0 /usr/lib/libgnome-keyring.so.0
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0.2.0 /usr/lib/libgnome-keyring.so.0.2.0
Now run the bin file again and it should work
$ sudo ./AdobeAIRInstaller.bin
