R 3.5.0不适用于Ubuntu 18.04
我刚刚在我的testbed笔记本电脑上安装了Ubuntu 18.04。 总新安装（选择’最小’选项）。 我做的前两件事是安装R 3.5和R Studio 1.1.453 。 如果我打开R的全新安装并让它闲置30分钟左右我最终得到错误"Error: Unable to establish connection with R session" 。
此时我无法在R Studio做任何事情，我必须将其重新加载并重新加载所有内容以继续编程。 互联网搜索显示，由于人们在使用GNOME的Ubuntu机器上安装R/R Studio ，因此这个问题一再出现。 我不确定GNOME是否是根本原因，但它很有趣。
有人解决了这个吗？ 或者你可能在Ubuntu 18.04上运行R 3.5没有问题。 请告诉我。 在此问题导致我的系统崩溃之前，我只能运行30分钟左右。 我的系统是Bionic Beaver的全新安装，只有R就可以了。 奇怪的。
——对于那些想知道的人——
R的安装是通过
sudo add-apt-repository "deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/" sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9 sudo apt-get update sudo apt-get install r-base r-base-dev
和R Studio通过此链接通过Ubuntu软件中心安装 https://download1.rstudio.org/rstudio-xenial-1.1.453-amd64.deb
据推测，R Studio的预览版本可以修复此问题（TBD） https://s3.amazonaws.com/rstudio-ide-build/desktop/trusty/amd64/rstudio-1.2.792-amd64.deb
我在干净的Ubuntu 18.04 LTS VM上做了一些步骤：
sudo add-apt-repository "deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/" sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9 sudo apt-get update sudo apt-get install r-base r-base-dev
然后试着跑R ：
然后安装RStudio：
cd ~/Downloads wget https://download1.rstudio.org/rstudio-xenial-1.1.453-amd64.deb sudo apt-get install ./rstudio-xenial-1.1.453-amd64.deb
它启动并正常运行：
之后我尝试了更新的版本，它也有效。
以下是与R相关的包裹清单：
