When I try to install Postler from the Elementary OS web page (first by adding the repository and running apt-get update, then clicking "Install," the Software Center opens, then displays a "Not Found" error. The package is also not found when searching for it in the Software Center or by installing it from the command line.
Is there something I am missing? Dexter installed just fine, and I've tried Postler on the elementary live image, and I like it better than Thunderbird, so I'd like to use it.
I'm running Ubuntu 11.04 with Unity, though Unity shouldn't affect it.
