sudo apt get-install g++ 未满足的依赖项

查看了几个有类似问题的问题，但没有任何解决方案。问题是：

$ sudo apt-get Install g++
The following packges have unmet dependencies:
g++ : Depends:g++-4.8 (>= 4.8.2-5~) but it is not going to be installed
E:Unable to correct problems, you have held broken packages.

从我尝试过的其他问题来看：

  • sudo apt-get update
  • sudo app-get -f Install*

  • sudo apt-cache policy g++-4.8

    g++-4.8:
Installed: (none)
Candidate: 4.8.2-19ubuntu1
Version table:
4.8.2-19ubuntu1 0
500 http://ca.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages

$ sudo apt-get install g++-4.8
The following packages have unmet dependencies:
 g++-4.8 : Depends: gcc-4.8-base (= 4.8.2-19ubuntu1) but 4.8.4-2ubuntu1~14.04 is to be installed
           Depends: gcc-4.8 (= 4.8.2-19ubuntu1) but 4.8.4-2ubuntu1~14.04 is to be installed
           Depends: libstdc++-4.8-dev (= 4.8.2-19ubuntu1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

$ apt-cache policy gcc-4.8-base gcc-4.8 libstdc++-4.8-dev; sudo apt-get install gcc-4.8-base gcc-4.8 libstdc++-4.8-dev
gcc-4.8-base and gcc-4.8 Installed=Candidate
but
libstdc++-4.8-dev:
Installed: (none)

我对这一切完全陌生，从闪存驱动器运行 ubuntu，只需要安装 g++。任何帮助都将不胜感激。

根据尝试过的建议：

sudo-apt 安装 aptitude

很多错误都说'Could not resolve archive.ubuntu.com'

答案1

终于搞明白了。谢谢@sinclair

通过将我的无线网络更改为另一个网络来解决网络问题，然后运行，sudo apt-get install aptitude最初sudo aptitude install build-essentials失败了，但通过内置故障排除，它给了我降级的选项，这解决了所有问题。现在我有了我需要的 g++。
