我正在使用 Linux Mint 14。每当我尝试使用 apt-get 安装或升级任何东西时，我都会收到以下消息：
The following packages have unmet dependencies.
google-chrome-stable :
Depends: libnss3 (>= 3.17.2) but 3.15.4-0ubuntu0.12.10.2 is to be installed
Depends: libstdc++6 (>= 4.8.0) but 4.7.2-2ubuntu1 is to be installed
Depends: lsb-base (>= 4.1) but 4.0-0ubuntu26.2 is to be installed
Google Chrome 似乎运行良好，我所做的一切似乎都无法解决这个问题。任何更新都只是以这条消息结束。
我试过了：

也没什么帮助。
还根据评论中的建议尝试了以下操作：
sudo apt-get install lsb-base libstdc++6 libnss3
Reading package lists... Done
Building dependency tree
Reading state information... Done
lsb-base is already the newest version.
libnss3 is already the newest version.
libstdc++6 is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies.
google-chrome-stable : Depends: libnss3 (>= 3.17.2) but 3.15.4-0ubuntu0.12.10.2 is to be installed
Depends: libstdc++6 (>= 4.8.0) but 4.7.2-2ubuntu1 is to be installed
Depends: lsb-base (>= 4.1) but 4.0-0ubuntu26.2 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
我需要用电脑工作，而且我非常忙，所以没有时间升级到 Mint 的新版本，而这本来是我的首选。有什么办法可以解决这个问题吗？
