Failed to install root-6.02.05 on ubuntu14.04(LTS)

If you set “ROOTSYS” for configure then you must execute “make install” -> in order to “fix” it now, execute (I assume that you built it in “/home/coordinator/soft/root-6.02.05”):
cd /home/coordinator/soft/root-6.02.05
export ROOTSYS=/home/coordinator/soft/root-6.02.05/root-6.02.05
make install

Looking at your “ROOTSYS” string, it seems to me that you try to keep the source code, too. In this case it would be better to build ROOT “in-place” (so “unset ROOTSYS” before running configure):
