I install root from source file https://root.cern.ch/download/root_v6.10.02.source.tar.gz
The cmake gave the following error:
CMake Error at cmake/modules/SearchInstalledSoftware.cmake:265 (message):
libXft and Xft headers must be installed.
Call Stack (most recent call first):
CMakeLists.txt:76 (include)
-- Configuring incomplete, errors occurred!
I then tried
sudo apt-get install libxft-dev
and got the following error:
E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/e/expat/libexpat1-dev_2.1.0-7ubuntu0.16.04.2_amd64.deb 404 Not Found [IP: 91.189.88.162 80]
