@ternaus gcc-4.9 may not be available on Ubuntu 18.04 anymore. But the message does note

So replacing "4.9" for e.g. "5" or "7" should work :)

For those who don't have root access and are in a conda environment, do this:
conda install -c psi4 gcc-5

This command delete my gpu driver and other driver softweres

At the same time I can't use the setting options

conda install -c psi4 gcc-5

One can also follow the instructions on GCC's homepage https://gcc.gnu.org/wiki/InstallingGCC after downloading the desired version

tar xzf gcc-VERSION.tar.gz
cd gcc-VERSION
./contrib/download_prerequisites
cd ..
mkdir objdir
cd objdir
$PWD/../gcc-VERSION/configure --prefix=$HOME/GCC-VERSION --enable-languages=c,c++,fortran,go
make
make install
