我不熟悉命令行并尝试将R安装到我的Google Cloud VM实例上。这是我的Ubuntu的版本。
Distributor ID: Debian
Description: Debian GNU/Linux 9.2 (stretch)
Release: 9.2
Codename: stretch
我一直在使用此链接指导我：http://cran.r-project.org/bin/linux/ubuntu
首先，我在我的source.list中添加了一个deb存储库。 我在source.list中添加的行是＆＃39; deb https://cran.ma.imperial.ac.uk/bin/linux/ubuntu utopic /＆＃39;。 然后我执行了以下操作。
kefei@pectendashboard:~$ sudo nano /etc/apt/sources.list
kefei@pectendashboard:~$ sudo apt-key adv --keyserver
keyserver.ubuntu.com --recv-keys E084DAB9
Executing: /tmp/apt-key-gpghome.Zdt2MbceSW/gpg.1.sh --keyserver
keyserver.ubuntu.com --recv-keys E084DAB9
gpg: key 51716619E084DAB9: "Michael Rutter <marutter@gmail.com>" not
changed
gpg: Total number processed: 1
gpg: unchanged: 1
我想知道＆lt; gpg是什么意思：找不到有效的OpenPGP数据。＆＃39;
kefei@pectendashboard:~$ sudo add-apt-repository ppa:marutter/rdev
The latest developmental version of R for testing packages

gpg: keybox '/tmp/tmp3c2s3m12/pubring.gpg' created

imported
gpg: Total number processed: 1
gpg: imported: 1
gpg: no valid OpenPGP data found.
当我运行apt-get update时出现更多错误，主要是404错误。例如：
kefei@pectendashboard:~$ sudo apt-get update
Ign:23 http://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu
bionic/main Translation-en_US
Err:12 http://ppa.launchpad.net/marutter/rdev/ubuntu bionic/main amd64
Packages
404 Not Found
然后是一系列警告和错误消息。

在此之后，我跑了'sudo apt-get upgrade＆＃39;和＆＃39; sudo apt-get install r-base＆＃39;，获取以下消息。
kefei@pectendashboard:~$ sudo apt-get install r-base
Reading package lists... 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 (>= 3.4.2-2xenial2) but it is not going
to be installed
Depends: r-recommended (= 3.4.2-2xenial2) 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.
我已经尝试了许多源代码和存储库来安装r-base，但是仍然会出现相同的错误消息。如果有人能帮助我，我将非常感激。
