由于依赖关系，无法升级R

Question

我想将R(3.0.2版)升级到3.4.1这样的更新版本，但我面临一个复杂的依赖问题，这阻碍了我这样做。

我使用几种解决方案在终端上输入了许多代码，但没有成功，您可以在下面看到升级它的尝试和警告消息：

    sudo apt-get install r-base
    The following information may help to resolve the situation:
    The following packages have unmet dependencies:
    r-base : Depends: r-base-core (>= 3.4.1-2xenial0) but 3.0.2-1ubuntu1   is to be installed
    Depends: r-recommended (= 3.4.1-2xenial0) but 3.0.2-1ubuntu1 is to  be installed

我在这个链接上执行了所有步骤，但是没有工作，结果是：

 sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
 sudo add-apt-repository 'deb [arch=amd64,i386] https://cran.rstudio.com/bin/linux/ubuntu xenial/'
 sudo apt-get update

在最后一段代码之后，我收到了以下消息：

 W: Some index files failed to download. They have been ignored, or old ones used instead.

在此之后，我遵循了这个链接和这个链接的步骤:当我运行sudo -f安装时

  Reading package lists... Done
  Building dependency tree       
  Reading state information... Done

当我运行sudo apt升级时，我得到：

任何形式的帮助都将不胜感激。

事先非常感谢

对不起，我在Linux方面的能力很差，但我正在努力!！

Answer 1

而不是仅仅

sudo apt-get install r-base

增加命令以包括apt表示冲突的包：

sudo apt-get install r-base r-base-core

你可能得在这里再加几个。这主要是因为你做了一个部分升级增加了回购，这里从CRAN。

但是我们中的很多人都使用这些CRAN插件，这应该可以工作(虽然我更喜欢最近的Ubuntu版本，但这是另一个故事)。
