我正在尝试在 Elementary OS 5.0 Juno 上安装 R 和 R Studio。在尝试了几种安装方法并尝试删除以前的软件包并开始全新安装后，我仍然收到以下错误，有人可以告诉我下一步该怎么做吗？
$ sudo apt-get install r-base r-base-dev

您使用的是 eOS Juno，它基于 Ubuntu 18.04 Bionic。我在错误中看到您尝试使用 Disco 版本，即 Ubuntu 19.xx。因此，请使用正确的版本。
如果你没有使用过不同的软件包，也许你应该尝试一下 Anaconda。在那里你也可以安装 R 和 RStudio，该工具会为你选择正确的版本。
