Linux package managers

On GNU/Linux Debian version >= 9, Ubuntu version >= 18.04, Arch Linux there are three packages to install

• sagemath (for the binaries)
• sagemath-jupyter (for the browser interface)
• and the documentation which is called sagemath-doc-en on Debian/Ubuntu and sagemath-doc on Arch Linux.

Gentoo users might want to give a try to sage-on-gentoo.
