无法安装python3-dev ubuntu

Question

当我试图安装python3-dev使用sudo apt-get install python3-dev我得到了以下信息

python3-dev : Depends: libpython3-dev (= 3.4.0-0ubuntu2) but it is not going to be installed
           Depends: python3.4-dev (>= 3.4.0-0~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

所以我尝试安装依赖项libpython3-dev然后我收到了这条消息

The following packages have unmet dependencies:
 libpython3.4-dev : Depends: libpython3.4-stdlib (= 3.4.0-2ubuntu1.1) but 3.4.3-1ubuntu1~14.04.1 is to be installed
                    Depends: libpython3.4 (= 3.4.0-2ubuntu1.1) but 3.4.3-1ubuntu1~14.04.1 is to be installed
E: Unable to correct problems, you have held broken packages.

但是，这两个依赖项都已安装。我使用的是 Ubuntu 14.04

当我跑apt-cache policy python3.4我得到

    python3.4:
    Installed: 3.4.3-1ubuntu1~14.04.1
  Candidate: 3.4.3-1ubuntu1~14.04.1
  Version table:

解决方案是等待 Ubuntu 开发人员将 Python 3.4.3 重新上传到更新存储库。这应该在任何一天发生。密切关注错误 #1348954。

编辑：固定。安装python3-dev再次工作。
