For some reason Adobe only supported Linux until Adobe AIR 2.6.
Download Adobe Air
Download Latest Version Air 2.6.0 For Linux http://airdownload.adobe.com/air/lin/download/2.6/AdobeAIRInstaller.bin (16,1 MB) wget http://airdownload.adobe.com/air/lin/download/2.6/AdobeAIRInstaller.bin
Install ia32-libs
The ia32-libs 32bit crap is needed if you want to run this in 64-bit Ubuntu.
sudo apt-get install ia32-libs
Install Adobe Air
chmod +x AdobeAIRInstaller.bin
sudo ./AdobeAIRInstaller.bin
You might get an error saying:
“Sorry, an error has occured. Adobe AIR could not be installed. Install either Gnome Keyring or KDE KWallet before installing Adobe AIR.
Then you need to link a few files:
Locate libgnome-keyring.so
locate libgnome-keyring.so
(my result, yours might differ)
/usr/lib/i386-linux-gnu/libgnome-keyring.so.0
/usr/lib/i386-linux-gnu/libgnome-keyring.so.0.2.0
/usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0
/usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0.2.0
Create a symbolic link to your location you found using the locate command:
sudo ln -s /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0 /usr/lib/libgnome-keyring.so.0
Retry install
chmod +x AdobeAIRInstaller.bin
sudo ./AdobeAIRInstaller.bin
Remove symbolic links after installation of Adobe AIR 2.6.0
sudo rm /usr/lib/libgnome-keyring.so.0
