我最近部署了投资组合应用程序。现在，我想通过不同的机器（linux mint 14）更新我的应用程序。所以，要更新我的应用程序，我肯定需要在我的机器上安装 heroku toolbelt，之后我可以继续处理剩下的事情。正确的？。但是，这里我的问题是“我无法在我的机器上安装 heroku toolbelt”。
在安装过程中显示以下错误
wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh

所以，在那之后我已经按照谷歌搜索，堆栈溢出搜索来解决问题。我正在尝试通过堆栈溢出识别的其他一些进程安装它，但它仍然没有解决我的问题并且它显示错误libnss3 依赖项为
libnss3-1d : Depends: libnss3 (= 3.13.1.with.ckbi.1.88-1ubuntu7) but 3.14.3-0ubuntu0.12.10.1 is installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
E: Unable to correct dependencies
为了支持 Google-chrome 浏览器，我已经用 libnss3.14.3-0ubuntu0.12.10.1 替换了这个 libnss3.13.1.with.ckbi.1.88-1ubuntu7。但是 Heroku 不支持它。如果我要安装以前版本的 libnss3，那么我应该删除 google-chrome。我需要 google chrome，因为它为调试和分析应用程序提供了最好的开发人员工具支持。
请帮我解决这个安装 heroku-toolbelt 的问题。
谢谢。
