我知道这个问题已经被问过了，但是发布的所有答案都无法帮助解决我的问题。我在 Ubuntu 14.04 上尝试了以下命令：
sudo apt-get install r-base-core
我得到：
The following packages have unmet dependencies:
r-base-core : Depends: libtiff4 but it is not installable
Recommends: r-recommended but it is not going to be installed
Recommends: r-base-dev but it is not going to be installed
Recommends: r-doc-html but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
我也尝试过 aptitude：
The following packages have unmet dependencies:
r-base-core : Depends: libtiff4 which is a virtual package.
The following actions will resolve these dependencies:
Keep the following packages at their current version:
1) r-base-core [Not Installed]
2) r-base-dev [Not Installed]
3) r-cran-boot [Not Installed]
4) r-cran-class [Not Installed]

然后我跑了apt-get upgrade，update其他东西描述在本教程。以下是 cat 命令的结果/etc/apt/sources.list：

答案1
非常感谢 Wilf 回答您的问题。但是其他人在 R 邮件列表中给了我答案，运行以下命令：
sudo add-apt-repository ppa:marutter/rrutter
sudo apt-get update
sudo apt-get install r-base r-base-dev
帮我解决了我的问题！
答案2
Depends: libtiff4 but it is not installable
此问题似乎是由于libtiff4软件包不适用于 Ubuntu 14.04
对于 i386：
wget http://mirrors.kernel.org/ubuntu/pool/universe/t/tiff3/libtiff4_3.9.7-2ubuntu1_i386.deb
dpkg -i libtiff4_3.9.7-2ubuntu1_i386.deb
对于 amd64：
wget http://mirrors.kernel.org/ubuntu/pool/universe/t/tiff3/libtiff4_3.9.7-2ubuntu1_amd64.deb
dpkg -i libtiff4_3.9.7-2ubuntu1_amd64.deb
然后您可能能够安装r-base-core- 如果此软件包在默认的 Ubuntu 存储库中可用，您可能需要提交错误报告，指出它没有所需的依赖项。
编辑：您要安装哪个版本？版本这里显然取决于libtiff5哪个可用......
答案3
这有帮助！
解决这个问题的另一种方法是：从以下网址下载所需的 .deb 格式的 R 软件/包https://cloud.r-project.org/bin/linux/ubuntu/xenial-cran35/并通过 Ubuntu 软件安装它。
