Short tutorial on how to install Adobe Air 2.x and TweetDeck on a 64bit Ubuntu Linux.

1. Go to http://get.adobe.com/de/air/ and grab the latest 32bit version of Adobe Air, which is 2.5.1 when writing this. Select the .bin version in the dropdown below.
2. Grab a copy of getlibs from here. (local copy)
3. Use GDebi to install the .deb or type in a terminal
   

   sudo dpkg -i getlibs-all.deb

4. Run getlibs and download the required libraries
   

   sudo getlibs -l libnss3.so.1d libnssutil3.so.1d libsmime3.so.1d libssl3.so.1d
   libnspr4.so.0d  libplc4.so.0d  libplds4.so.0d libgnome-keyring.so libgnome-keyring.so.0
   libgnome-keyring.so.0.1.1

5. Run ldconfig to update the necessary links to the shared libraries
   

   sudo ldconfig

6. Make the downloaded Adobe Air Installer executable and install Adobe Air
   

   sudo chmod +x AdobeAIRInstaller.bin
   sudo ./AdobeAIRInstaller.bin

Now the installation of TweetDeck. The default installation path for TweetDeck is in /opt, which suits my preferences. Since the installer needs the right to write to the installation directory (really! :) ), I create a new subfolder and change the ownership of it my user.

1. Create directory and change ownership
   

   sudo mkdir /opt/TweetDeck
   sudo chown $USER /opt/TweetDeck

2. Go to http://www.tweetdeck.com/desktop/, click the „Install TweetDeck“ Button and change the installation path to /opt/TweetDeck. If you don’t have flash installed/enabled, download the .air file from here.
3. If you’re not running Gnome or KDE, take a look at this small script to make TweetDeck start without error. When you followed this tutorial, you have to make a small change to the script. Replace the line
   

   DIRNAME=”/opt/TweetDeck/bin”

   with

   DIRNAME=”/opt/TweetDeck/TweetDeck/bin”

4. Follow me in your fresh installed TweetDeck on 64Bit Ubuntu. :)
