答案1
我添加了错误的代表：
sudo add-apt-repository 'deb [arch=amd64,i386] https://cran.rstudio.com/bin/linux/ubuntu xenial/'
应该
sudo add-apt-repository 'deb [arch=amd64,i386] https://cran.rstudio.com/bin/linux/ubuntu artful/'
答案2
您应该首先通过运行以下命令删除错误的“xenial”存储库：
sudo add-apt-repository -r 'deb [arch=amd64,i386] https://cran.rstudio.com/bin/linux/ubuntu xenial/'
然后r-base-core运行安装：
sudo apt install r-base-core
