未满足的依赖项：libjpeg8 (>= 8c)，但在安装 R 时无法安装

当尝试在 Debian 9 (stretch) 上安装 R 时，我遇到了未满足的依赖关系。具体来说，运行：

$ sudo apt-get install r-base-core

结果是

           Recommends: r-doc-html but it is not going to be installed

有人可以帮忙吗？我已经用谷歌搜索了这个问题，但无法想出任何解决办法。

谢谢

答案1

未满足的依赖关系可能源于您的存储库引用的版本混合，特别是针对 Ubuntu 14.04 的 CRAN 存储库。您应该删除（或用 注释掉#） 中的以下条目/etc/apt/sources.list以及 中的任何文件/etc/apt/sources.list.d：

  • http://cran.rstudio.com/bin/linux/ubuntu trusty/;
  • 所有ftp.uk.debian.org引用 的条目jessie。

完成此操作后，apt update再次运行apt install r-base-core不应再因缺少libjpeg8.

答案2

要安装libjpeg8-dev，请使用以下命令：

sudo apt install aptitude
sudo aptitude install libjpeg-dev

然后您可能需要选择“否”、“是”、“是”。请参阅我的详细说明：如何pdftoppm在 Linux Ubuntu 上安装/升级到最新版本的 Poppler/（撰写本文时版本 22.11.0）
