我想用ubuntu从3.0.3更新到R到3.1.2。我正在研究Ubuntu 14.04LTS，64位。更新R版本从3.0.3到3.1.2
我做了以下内容：
cd /etc/apt/
sudo gedit sources.list
我添加下面一行：
deb http://cran.rstudio.com/bin/linux/ubuntu trusty/
然后：
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install r-base
某些文件被上传。
然后我检查将R版本：
sudo R
version
platform x86_64-unknown-linux-gnu
arch x86_64
os linux-gnu
system x86_64, linux-gnu
status
major 3
minor 0.3
year 2014
month 03
day 06
svn rev 65126
language R
version.string R version 3.0.3 (2014-03-06)
nickname Warm Puppy
我仍然有3.0.3版本，有人可以帮我升级到3.1.2？

可能从linux安装的'cran.r-project.org'页面抓取这个链接？ http://cran.r-project.org/bin/linux/ubuntu/trusty/r-base-core-dbg_3.1.2-1trusty0_amd64.deb – 2014-12-03 13:12:53
什么是sudo apt-get dist-upgrade给你？ – ECII 2014-12-03 13:28:06
你可以确定密钥是否已经成功添加到'sudo apt-key list'中？它应该在底部附近。另外，由于R已经安装，因此您不需要使用'install r-base'命令。将repo添加到sources.list应该允许'sudo apt-get update && sudo apt-get upgrade'工作。 – cdeterman 2014-12-03 13:28:40
