I just checked the glx-dock.org repository, and all the packages are at the "2.1.3-10-lucid" version. So upgrading your package manager should solve the problem. For example, you can try a "sudo apt-get update && sudo apt-get dist-upgrade" in a terminal to achieve that; however using Ubuntu's update-manager may be more friendly :-) On Thu, Apr 22, 2010 at 8:22 PM, Christophe Chapuis <
