E:找不到尼泊尔-核心-dev软件包

Question

我已经安装了Ubuntu12.04，我希望安装nepomuk-core-dev来构建等离子媒体中心( http://sinny.in/node/25 )，但是我得到了以下错误：

vijay13@ubuntu:~/plasma-mediacenter/build$ sudo apt-get install nepomuk-core-devReading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package nepomuk-core-dev

and following error while building :
-- Found KDE4Workspace: /usr/lib/cmake/KDE4Workspace/KDE4WorkspaceConfig.cmake 
CMake Error at CMakeLists.txt:7 (find_package):
  Could not find module FindNepomukCore.cmake or a configuration file for
  package NepomukCore.

  Adjust CMAKE_MODULE_PATH to find FindNepomukCore.cmake or set
  NepomukCore_DIR to the directory containing a CMake configuration file for
  NepomukCore.  The file will have one of the following names:

    NepomukCoreConfig.cmake
    nepomukcore-config.cmake

sudo add-apt-repository ppa:kubuntu-ppa/backports和sudo apt-get update解决了问题。

您所遵循的指南只适用于12.10及以上。它不会在12.04上起作用。nepomuk-core-dev包没有包含在精确的(12.04)存储库中。您必须使用Quantal或更高版本来直接在您的存储库中获取包。因为构建软件是推荐使用最新版本的Ubuntu，而不是长期支持(LTS)，因为较新的版本有较新的包，如果您需要从源代码构建(通常，软件开发人员保持他们的库更新)。

要查看Ubuntu的哪个版本，请检查http://packages.ubuntu.com/nepomuk-core-dev
