I am having the following errors trying to install R: The following packages have unmet dependencies: r-base : Depends: r-base-core (>= 3.3.1-1xenial0) but it is not going to be installed Depends: r-recommended (= 3.3.1-1xenial0) 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. I tried: Uninstall old R: sudo apt-get remove r-base-core Then: sudo gedit /etc/apt/sources.list Add the following to the file: deb http://cran.rstudio.com/bin/linux/ubuntu precise/ and exit gedit. Then copy/paste these commands into the command line: sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9 sudo add-apt-repository ppa:marutter/rdev sudo apt-get update sudo apt-get upgrade sudo apt-get install r-base Still not working, any suggestions? Update Fixed this issue. I needed to edit the etc/apt/sources.list file to point to trusty and not xenial
