Tweetdeck on Linux, security problem (+fix)

Posted by Treg in HOWTO Ubuntu, Linux, Tech

While testing KDE4.5, it seemed I couldn’t use Tweetdeck anymore. The problem has something to do with storing passwords securely. Since Adobe AIR is a 32-bit application, it needs the 32-bit version of the KDE wallet client libraries in order to get the AIR ELS working properly. (Similarly on GNOME, the 32bit libraries for GNOME keyring are used.)

You can check if 32bit kdewallet client libraries are installed by testing the dynamic link dependencies of e.g. Adobe AIR’s

ldd "/opt/Adobe AIR/Versions/1.0/Resources/" | grep kwallet

If you get something like “ => not found” you will need to install the 32bit library. In Ubuntu 9.10 this library is in the kdelibs4c2a package, but this can be detected automatically by the getlibs package (see

sudo dpkg -i getlibs-all.deb
sudo getlibs
sudo ldconfig

Re-run the ldd command above to check that the client library can now be resolved.

After this, erase Adobe AIR ELS and enter your account data anew:

rm -rf ~/.appdata/Adobe/AIR/ELS

After this, AdobeAIR shows up in KDE wallet manager with an ELSKey stored password.
