【问题描述】：
按照站点 [here] 上的说明安装 R 语言。
在安装过程中，我使用 apt-get install 命令在 r-base 组件处收到错误“unmet dependencies”。使用以下命令序列查看日志：
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
r-base : Depends: r-base-core (>= 3.4.0-1xenial0) but it is not going to be installed
Depends: r-recommended (= 3.4.0-1xenial0) but it is not going to be installed
Recommends: r-base-html but it is not going to be installed
Recommends: r-doc-html but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
这是我的安装过程中的一个错误，还是这个数据包损坏了？

我在 ubuntu 16.04 的 dockerfile 中尝试了相同的步骤，并且成功了。我唯一需要更改的是获取密钥的网址：
hkp://keyserver.ubuntu.com:80，但不要认为它与它有关。 -
