http://askubuntu.com – As I use Zinio a lot, I need to install Adobe Air on my Ubuntu 12.04. Unfortunately the installation failed with message: Sorry, an error has occured. Adobe AIR could not be installed. Install either Gnome Keyring or KDE KWallet before installing Adobe AIR. On Ubuntu 11.10 it was still possible to install Adobe Air without any problem. (HowTos)
