我曾尝试在我的 Ubuntu 16.10 Yakkety 上安装 R。
我将以下 deb 放在我的 /etc/apt/sources.list 文件中。
deb http://cran.ma.imperial.ac.uk/bin/linux/ubuntu yakkety main
universe restricted multiverse
但是，运行后sudo apt-get update，我收到以下消息，我不明白：
Fetched 102 kB in 6s (15.7 kB/s)
Reading package lists... Done

在 Ubuntu 16.10 中安装 R 时有人遇到过这种情况吗？
答案1
您忘记导入此存储库的 pgp-key。因此报告错误。
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9随后添加密钥运行sudo apt update。
这里有一个关于如何添加其存储库的详细说明：http://cran.ma.imperial.ac.uk/bin/linux/ubuntu/README
答案2
您的文件中的行sources.list应该是：
deb https://cran.ma.imperial.ac.uk/bin/linux/ubuntu yakkety/
您不需要“main”之类的。
然后，阅读说明安全 APT在https://cran.r-project.org/bin/linux/ubuntu/.apt抱怨无法验证来自服务器的包。
