在Ubuntu 16上安装R语言 – 未满足的依赖关系
按照站点上的说明安装R语言[ here ]。
在安装过程中，我使用apt-get install命令在r-base组件上收到一个错误“ unmet dependencies ”。 按照以下命令序列查看日志：
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9 Executing: /tmp/tmp.QQyv0HB7mS/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9 gpg: requesting key E084DAB9 from hkp server keyserver.ubuntu.com gpg: key E084DAB9: "Michael Rutter <marutter@gmail.com>" not changed gpg: Total number processed: 1 gpg: unchanged: 1 /data/shared/datascience# add-apt-repository 'deb [arch=s390x] https://cran.rstudio.com/bin/linux/ubuntu xenial/' apt-get update Hit:1 https://cran.rstudio.com/bin/linux/ubuntu xenial/ InRelease Hit:2 http://ports.ubuntu.com/ubuntu-ports xenial InRelease Get:3 http://ports.ubuntu.com/ubuntu-ports xenial-updates InRelease [102 kB] Get:4 http://ports.ubuntu.com/ubuntu-ports xenial-security InRelease [102 kB] Get:5 http://ports.ubuntu.com/ubuntu-ports xenial-updates/main s390x Packages [554 kB] Get:6 http://ports.ubuntu.com/ubuntu-ports xenial-updates/universe s390x Packages [494 kB] Fetched 1252 kB in 12s (104 kB/s) Reading package lists... Done apt-get install r-base 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 (>= 3.4.0-1xenial0) but it is not going to be installed Depends: r-recommended (= 3.4.0-1xenial0) but it is not going to be installed Recommends: r-base-html 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. 这是我的安装过程中的错误，还是这个包被破坏？
通过使用下面显示的通用Ubuntu存储库和命令，问题得以解决：
sudo apt-get install r-base r-base-dev
