Hello readers! Good to see you again. Today, I'd like to write a step-by-step guide on how to install Adobe AIR on Ubuntu 12.04 LTS Precise Pangolin. Adobe AIR (Adobe Integrated Runtime) is a cross platform application runtime which allows us to run Rich Internet Application (RIA) on Windows, Linux, Mac, and even mobile devices.

First thing first, please download the Adobe AIR installer by running the following command:
  • wget http://airdownload.adobe.com/air/lin/download/latest/AdobeAIRInstaller.bin
Once downloaded, you need to add "execute" permission to the installer:
  • sudo chmod +x AdobeAIRInstaller.bin
The last thing to do is executing the Adobe AIR installer:
  • sudo ./AdobeAIRInstaller.bin
You may encounter this following error message while installing:

To solve this kind of problem, please run the following command:
For 32bit system:
  • 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

For 64bit system:
  • 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
Then run the installer again.

If everything done well, you should be able to access Adobe AIR application installer in Unity Dash.

Enjoy :)
