Installation from source (replace root_install with for example 6.24.06):

# The latest stable branch gets updated automatically on each release. 
# You may update your local copy by issuing a `git pull` command from within `root_src/`.
git clone --branch latest-stable https://github.com/root-project/root.git root_src
mkdir root_build root_install && cd root_build
cmake -DCMAKE_INSTALL_PREFIX=../root_install ../root_src # && check cmake configuration output for warnings or errors
cmake --build . -- install -j4 # if you have 4 cores available for compilation
source ../root_install/bin/thisroot.sh # or thisroot.{fish,csh}
