Debian Wheezy，apt-get 有未满足的依赖关系

几乎我尝试的任何涉及的命令apt-get都会给我一个错误，告诉我我应该运行apt-get -f install，但这给了我这个错误：

似乎gcc-4.7缺失是个问题，但如果我尝试apt-get install gcc-4.7

root@vps148794:~# apt-get install gcc-4.7

gcc-4.7 is already the newest version.
gcc-4.7 set to manually installed.
You might want to run 'apt-get -f install' to correct these:

为什么会发生这种情况？如何恢复 apt-get 以便可以安装东西？我完全无法安装，因为无论我尝试安装什么都会出现此错误。也许这能有所帮助？

答案1

你真的应该好好想想你在这里做什么。Debian Wheezy 现在完全不受支持，而且在某个时候（我不记得是否已经宣布过）它将从（主）镜像中删除。

答案在于gcc-4.7已安装和gcc-4.7-base编辑显示未安装之间的区别。安装它应该会有所帮助。（我真的无法解释你为什么会陷入那种境地。）

还有一件事：我不知道 izzysoft.de repo 里有什么，但它似乎是为 ubuntu 制作的，混合这样的存储库可能会非常危险。
