If you try to install them into ~/texmf you can get into very frustrating problems.

In this case we are installing them into texlive 2018.

The path to getnonfreefonts and updmap-sys may vary according to how you installed texlive.

wget https://tug.org/fonts/getnonfreefonts/install-getnonfreefonts
texlua install-getnonfreefonts
/usr/local/texlive/2016/bin/x86_64-linux/getnonfreefonts --sys -a
/usr/local/texlive/2016/bin/x86_64-linux/updmap-sys

It’s important to call getnonfreefonts with the --sys option, and to use updmap-sys, rather than just updmap.
