Xubuntu 16.04 上的 R 升级/安装

Question

我试图在 Xubuntu 16.04 上将我的 R 从 3.4.4 升级到 3.5。
我按照这个指示

进入文件:computer/etc/apt/sources.list 其他软件添加deb
http://www.icesi.edu.co/CRAN/bin/linux/ubuntu xenial-cran35/<---
根据当前版本更改“-cran35”
"https://cran.r-project.org/bin/linux/ubuntu/ "

打开终端(Ctrl+Alt+T)在终端上写:sudo apt-get update在终端上输入您的 PC session 的密码:
sudo apt-get
install r-base 重启电脑

然而，在 sudo apt-get install r-base ，我收到以下错误:

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-recommended (= 3.5.1-1xenial) but it is not going to be installed E: Unable to correct problems, you have held broken packages.

这是依赖错误吗？我所做的是我必须确保添加了 APT 安全 key 。

我通过删除旧的 CRAN deb 源解决了我自己的问题:
