The following error message means that you cannot use the official Enigmail packages with Thunderbird as provided by your distribution: "Enigmail" could not be installed because it is not compatible with your Thunderbird build type (Linux_x86_64-gcc3). Please contact the author of this item about the problem.
In particular, releases shipped with Linux distributions (such as Ubuntu, Redhat, OpenSuSE or Debian) cannot be supported. If you want to use Thunderbird / SeaMonkey / IceDove / IceApe created and installed by your distribution, then you also need an Enigmail release created by the same distribution. A 64-bit version of Enigmail for Linux is provided on the Enigmail downloads page, but there is no guarantee that it will work with a specific distribution.
