grive-tools :取决于:libcurl4 4-openssl-dev，但是它不会被安装。

Question

最近，我尝试安装Grive工具，遵循这个网站带有Grive和Grive工具的客户端的说明。所有操作都很完美，直到我应用了命令sudo apt-get install grive-tools为止。出现了以下错误：

grive-tools : Depends: libcurl4-openssl-dev but it is not going to be installed

我在网上搜索了很多，我发现很多人说apt-get -f install会解决这个问题，比如无法在Ubuntu14.04中安装grive工具。

我尝试了所有建议的解决方案，大多数时候我都会出现以下错误：

The following packages have unmet dependencies:
 libgnutls-dev : Depends: libgnutls-openssl27 (= 2.12.23-12ubuntu2.1) but 3.2.16-1u1~ppa2 is installed.
 libcurl4-openssl-dev : Depends: libcurl3 (= 7.35.0-1ubuntu2.3) but 7.37.1-1u3~ppa1 is installed.

萨诺斯在问题中的回答

解决我的问题的唯一方法是在这里找到如何在添加PPA之后解决未满足的依赖关系？。

我应用了以下命令：

sudo apt-get update
sudo apt-get install aptitude

然后,

sudo aptitude install grive-tools

作为最后一步，我不得不降低一些包的级别以满足依赖关系。工艺样本列于：

sudo aptitude install grive-tools
