我正在尝试在 Ubuntu 上安装 R。我比较新，缺乏经验，所以可能犯了一个愚蠢的错误。我正在运行 Ubuntu 19.04
我正在使用 apt 安装 R：sudo apt-get install r-base
当我运行这个时出现这个错误：
Reading package lists... Done
Building dependency tree
Reading state information... Done
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-base-core (>= 3.6.3-1bionic) but it is not going to be installed
Depends: r-recommended (= 3.6.3-1bionic) but it is not going to be installed
Recommends: r-base-html but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
我看过这个问题：添加 PPA 后如何解决未满足的依赖关系？寻求帮助。
我跑了
sudo apt-get updatesudo apt-get upgrade（0 表示升级，0 表示全新安装，0 表示删除，0 表示不升级。）
这些运行起来没有问题。
然后我就跑了sudo apt-get -o Debug::pkgProblemResolver=yes dist-upgrade
对此的回应是：

Calculating upgrade... Done
The following packages have been kept back:
wine-stable
0 to upgrade, 0 to newly install, 0 to remove and 1 not to upgrade.
因此我删除并重新安装了 wine-stable。重新运行调试时没有显示任何软件包。
我认为我的问题可能是由于我的 PPA 中的某些内容造成的。我禁用了其中几个。

这是一个简单的修复。bionic-cran35 正在尝试运行，因为它存在于 source.list 中。这是之前安装失败的结果。注释掉
deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/
代码中的行已经修复了这个问题。
Bionic 源自以前的 Ubuntu 发行版，并已于 19.04 被 Disco 取代。
感谢@steeldriver 指出我的缺点。
