This is a post I’m creating about 50% because I want an easy-to-find reference for myself, but maybe someone will find it useful too.

1. Go to the Hugo releases page
2. Click “show all assets”
3. Copy the URL for the hugo_extended_{version}_Linux-64bit.tar.gz version
4. cd to wherever you will download it
5. wget {url}
6. tar -xsf hugo_{version}_Linux-64bit.tar.gz
7. mv hugo /root/.local/bin/
8. Rebuild the site
9. Remove old versions

I prefer to use the non-extended version most of the time, because I rarely need to rebuild CSS. So then repeat steps 3-7 with hugo_{version}_Linux-64bit.tar.gz.

When making a CSS change, repeat steps 6-7 & rebuild with the slower extended version. Then repeat 6-7 again to go back to the faster non-extended version.
