无法在 Ubuntu 19.10 上安装 r-base；未满足的依赖关系 r-推荐

Question

一般来说，我是使用 Ubuntu (19.10;eoan) 的新手，目前正在尝试安装 r-base。 r-base-dev 已安装。 当我这样做时，我收到以下消息：

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 r-base : Depends: r-recommended (= 3.6.2-1xenial) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

我已使用以下线程来尝试解决我的问题 - 没有任何成功。

Installing r-base; Depenency: r-recommended missing?

Issues in installing r-base-dev

为此，我停在了“禁用/删除/清除 PPA：”部分。因为我无法理解这个过程。

我将不胜感激任何解决我的问题的解决方案或建议。

如果没有关于您实际尝试过的内容（和订单）的更多信息，很难尝试确定它为什么不起作用，但我最近在 19.10 上自己安装了它。我用了以下。

# Get the key from the keyserver.
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9

# Add the repository to your sources.list. Make sure that it does not already exist
# and that it is not a typo in there. Making a backup of the file before running the
# next line is useful.
echo "deb https://cloud.r-project.org/bin/linux/ubuntu eoan-cran35/" | sudo tee -a /etc/apt/sources.list

# Install base, dev and other dependencies.
sudo apt install r-base r-base-dev r-cran-curl r-cran-openssl r-cran-xml2 libssl-dev libxml2-dev libcurl4-openssl-dev

它对我来说没有任何问题。将正确的存储库添加到 sources.list 非常重要。从错误消息来看，您使用的是指 Ubuntu Xenial 而不是 Ubuntu Eoan 的存储库。
