尝试安装 R 3.6.1，但在 ubuntu 中遇到问题

我正在 ubuntu (18.04) 中安装 R 的最新更新。我查看了许多以前的建议，但仍无法解决问题。我仍在尝试，任何帮助或建议都将非常有用。

sudo apt-get install r-base

您尝试安装 19.04 ( disco) 版本，r-base而您正在使用 18.04 ( bionic)，这就是引发错误的原因。

您必须删除disco存储库。

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

然后将其替换为bionic与您当前系统兼容的版本。

sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/'
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
sudo apt-get update
sudo apt-get install r-base
