How can I install Adobe AIR?

1. Download Latest Version Air 2.6.0 For Linux to your Desktop:

   • http://airdownload.adobe.com/air/lin/download/2.6/AdobeAIRInstaller.bin – 15.4Mb or find runtime files in Archived Adobe AIR SDK versions

     2. Ctrl+Alt+T to open terminal

     3. sudo apt-get install ia32-libs – (32bit rubbish if you want to run this in x64 Ubuntu; if you have trouble, see “Depends: ia32-libs-multiarch but it is not installable” – Solution)

     4. cd Desktop (change dir. to Desktop dir.)

     5. chmod +x AdobeAIRInstaller.bin (change mode – execute permission yes)

     6. ./AdobeAIRInstaller.bin
        (after you accept the Adobe Air license, it will prompt you for your password; it needs root access in order to install)

Maybe you’ll get an error after the last command?

Sorry, an error has occurred. Adobe AIR could not be installed. Install either Gnome Keyring or KDE KWallet before installing Adobe AIR.

This can be fixed:

• In a terminal (default shortcut: Ctrl+Alt+T), type:

  locate libgnome-keyring.so
  

• This is my result (yours might be different):

  /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0
  /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0.2.0
  

• As suggested below by @jmendeth, the easiest way to tell the installer where to find these files is to use LD_LIBRARY_PATH:

  • For 32-bit Ubuntu (tested on 12.04):

    LD_LIBRARY_PATH=/usr/lib/i386-linux-gnu ./AdobeAIRInstaller.bin
    

  • For 64-bit Ubuntu, the command line would probably be:

    LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu ./AdobeAIRInstaller.bin
    

If the LD_LIBRARY_PATH trick doesn’t work, you can try this:

• Create a symbolic link to your location strings that you found with the previous commands:

  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
  

• Use following commands for 32-bit systems:

  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 repeat step 4 & 6 (skip 5, as the permission to execute the file hasn’t changed).

• Remove symbolic links after installation of Adobe AIR 2.6.0:

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