在Ubuntu 20.04中安装R

Question

我想在Ubuntu 20.04上重新安装R， 当我使用以下命令时：

 sudo apt-get update 

I get the following error

关于从源代码安装的问题，我在这里发布了一份指南：https://stackoverflow.com/questions/70677307/installing-r-4-1-from-source-on-newly-installed-ubuntu-20-04 - JALO - JusAnotherLivngOrganism

应参考官方的 R 文档，其中也有关于解决密钥真实性的说明：https://cran.r-project.org/bin/linux/ubuntu/fullREADME.html - Vivek Atal

Answer 1

今天我在keyserv.ubuntu.com发现了一把新的密钥:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 95c0faf38db3ccad0c080a7bdc78b2ddeabc47b7.

前一个密钥已过期。

Answer 2

您没有指定使用的Ubuntu版本，但是this guide可能会有所帮助。

简而言之，首先安装传输工具 ´sudo apt install apt-transport-https software-properties-common´

然后将其密钥添加到apt存储库中

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9

移除其他R的清单，然后代之以此

sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/'

然后您可以像往常一样使用r-base进行安装。

sudo apt update
sudo apt install r-base

请通过 R --version 命令检查您是否已正确安装 R。
