Question

运行命令sudo apt-get install libstdc ++时，我在Ubuntu上得到以下输出：

libstdc++6 is already the newest version.
libstdc++6-4.6-dev is already the newest version.
libstdc++6-4.6-dev set to manually installed.
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

    The following packages have unmet dependencies:
     libstdc++6-4.5-dbg : Conflicts: libstdc++6-4.4-dbg but 4.4.7-1ubuntu2 is to be installed

我已经运行了showhold命令（apt-mark showhold） - 什么都没有。

如何解决要安装4.4.7-1ubuntu2 之类的冲突？

谢谢托马斯

有问题的软件包恰好已经安装好了。

libstdc++6 is already the newest version.
libstdc++6-4.6-dev is already the newest version.
libstdc++6-4.6-dev set to manually installed.

仅仅输入apt-get install libstdc ++会尝试在包管理器上安装每个版本的libstdc ++（6.4.5 docs / debug，而当前版本实际上是6.4.6）所以你应该具体说明哪个版本您要安装的软件包：

# apt-get install libstdc++6
