# Welcome to the SageMath Installation Guide¶

You can install SageMath either from a package manager, a pre-built binary tarball or from its sources.

Installing SageMath from your distribution package manager is the preferred and fastest solution (dependencies will be automatically taken care of and SageMath will be using your system Python). It is the case at least for the following GNU/Linux distributions: Debian version >= 9, Ubuntu version >= 18.04, Arch Linux, and NixOS. If you are in this situation, see Linux package managers.

If your operating system does not provide SageMath, you can also use a pre-built binary. See the section Install from Pre-built Binaries.

Or you could install the sage package from the conda-forge project. See the section Install from conda-forge.

By compiling SageMath from its sources you might be able to run a slightly more up-to-date version. You can also modify it and contribute back to the project. Compiling SageMath might take up to 4 hours on a recent computer. To build SageMath from source, go to the section Install from Source Code.

Note that there are other alternatives to use SageMath that completely avoid installing it:

• the Sage Debian Live USB key: a full featured USB key that contains a whole Linux distribution including SageMath. This might be an option if you fail installing SageMath on your operating system.
• CoCalc: an online service that provides SageMath and many other tools.
• Sage Cell Server: an online service for elementary SageMath computations.
• Docker images: SageMath in a container for more experienced users.

The rest of this document describes how to install SageMath from pre-built binaries and from sources.
