RStudio
 RStudio is a set of integrated tools designed to help you be more productive with R. It includes a console, syntax-highlighting editor that supports direct code execution, as well as tools for plotting, history, and workspace management.

Answer 1

当时使用Ubuntu 18.04LTS和KDE等离子体(可能是兼容的问题)，但现在使用Kubuntu 20.04LST，安装.

# update indices
apt update -qq

# install two helper packages we need
apt install --no-install-recommends software-properties-common dirmngr

# import the signing key (by Michael Rutter) for these repo
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9

# add the R 4.0 repo from CRAN -- adjust 'focal' to 'groovy' or 'bionic' as needed
add-apt-repository "deb https://cloud.r-project.org/bin/linux/ubuntu $(lsb_release -cs)-cran40/"

:~$ sudo dpkg -i rstudio-1.4.1717-amd64.deb

Answer 2

首先，我建议安装系统的所有更新，删除标记为自动删除的包。

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get autoremove --purge

然后通过以下方式安装R包

sudo apt-get install --reinstall r-base-dev

那么您应该知道RStudio为支持的Ubuntu18.04LTS(仿生海狸)提供了正确的构建deb包，您可以使用

cd ~/Downloads
wget -c https://download1.rstudio.org/desktop/bionic/amd64/rstudio-1.4.1717-amd64.deb

sudo apt-get install ./rstudio-1.4.1717-amd64.deb
