由于依赖关系无法升级 R
Can't upgrade R because of dependency
我想将 R（3.0.2 版）升级到 3.4.1 等较新的版本，但我遇到了一个复杂的依赖性问题，这使我无法执行此操作。
我使用多种解决方案在终端上输入了许多代码，但没有成功，您可以在下面看到我尝试升级它和警告消息：
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
我按照此 link 的所有步骤进行操作，但没有成功，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
在最后一个代码之后，我收到了以下消息：
W: Some index files failed to download. They have been ignored, or old ones used instead.
之后，我按照 link and this link 上的步骤操作：
当我 运行 sudo apt-get -f install 我得到
Reading package lists... Done
Building dependency tree
Reading state information... Done
当我 运行 sudo apt-get upgrade 我得到：
