Adobe Air is only available for 32 bits platform and can be downloaded here. To install it on 64 bits you'll need the following:
1. Add i386 platform and update your repositories:
# dpgk --add-architecture i386 # aptitude update
2. Since it's a 32 bits binary, you need to install ia32-libs-gtk:
# aptitude install ia32-libs-gtk
3. Start the binary (using sudo is important - launching it directly in root may fail):
$ sudo ./AdobeInstaller.bin
If you enconter "File Not found" error, you are missing libgcc1 package (which should have been installed with ia32-libs-gtk!).
If you get an error related to gnome-keyring / kwallet, you need to do a (temporary) symlink to one of these depending on your environment (Gnome -> gnome-keyring, KDE -> kwallet). For Gnome:
If you get error an installation is already in progress", you need to run it using "sudo".
$ find /usr/lib -name 'libgnome-keyring*' /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0.2.0 /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0
Then add simlinks:
$ sudo ln -s /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0.2.0 /usr/lib/libgnome-keyring.so.0.2.0 $ sudo ln -s /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0 /usr/lib/libgnome-keyring.so.0
4. Installation should now complete with no further error.
