如何在Raspbian /Linux 10 (buster)上安装R4.0.*？

Question

我相信我已经按照相关CRAN站点的指示更新了R到最新版本(目前R4.0.5)，但没有运气。

我在跑

$ cat /etc/os-release
PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"

与R版本

$ R --version
R version 3.5.2 (2018-12-20) -- "Eggshell Igloo"

我所做的是，首先向/etc/apt/sources.list添加存储库

http://cloud.r-project.org/bin/linux/debian buster-cran40/ 

目前的情况如下：

deb http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi
deb http://cloud.r-project.org/bin/linux/debian buster-cran40/

第二，获取和导入当前签名密钥：

$ sudo apt-key adv --keyserver keys.gnupg.net --recv-key 'E19F5F87128899B192B1A2C2AD5F960A256A04AF'

第三,

$ sudo apt update
$ sudo apt upgrade

现在我试图安装，但失败了。

$ sudo apt-get install r-base r-base-dev

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 r-base : Depends: r-base-core (>= 4.0.5-1~bustercran.0) but 3.5.2-1 is to be installed
          Depends: r-recommended (= 4.0.5-1~bustercran.0) but it is not going to be installed
          Recommends: r-base-html but it is not going to be installed
 r-base-dev : Depends: r-base-core (>= 4.0.5-1~bustercran.0) but 3.5.2-1 is to be installed
E: Unable to correct problems, you have held broken packages.

为了解决这个问题，我尝试了几种方法，比如修复依赖关系问题，

$ sudo apt-get autoremove

重新安装r-base-core，

$ sudo apt update 
$ sudo apt remove r-base-core
$ sudo apt install r-base-core

并在上面提到的CRAN站点上使用命令。

$ sudo apt install -t buster-cran40 r-base

但是我仍然有RV3.5.2，也就是说，我总是得到R3.5.2而不是R4.0.5。

我如何得到R4.0.5在我的覆盆子皮？
