1. sudo vi /etc/apt/source.list

在 /etc/apt/source.list中加入

deb  https://mirrors.tuna.tsinghua.edu.cn/CRAN//bin/linux/ubuntu artful/

2. sudo apt-get update

这一步，出现一个错误：

E: The repository ‘http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu bionic Release’ does not have a Release file.

解决方法，在software sources— —other software中将勾掉http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu bionic main

3.添加PPA

sudo add-apt-repository ppa:marutter/rrutter3.5

4.跟新R

sudo apt install r-api-3.5
