Installing Macaulay2 in Linux

• APT-based distributions
  • Ubuntu
  • Debian
• RPM-based distributions
  • Fedora
  • Red Hat Enterprise Linux
• Homebrew on Linux

APT-based distributions

Debian and its derivatives use the apt package manager. Macaulay2 has been available in the official Debian repositories since 2020, so you may install it using

sudo apt install macaulay2

Unless you are running Debian unstable or testing, this will likely be a slightly out-of-date version. The Macaulay2 developers host packages for the latest version of Macaulay2 in third-party repositories.

Ubuntu

Macaulay2 packages are available for all supported releases of Ubuntu (currently 18.04, 20.04, 22.04, 24.04, 24.10, and 24.05). Run the following:

sudo add-apt-repository ppa:macaulay2/macaulay2
sudo apt install macaulay2

Alternatively, if you would like to try out the latest development version of Macaulay2, run the following:

sudo add-apt-repository ppa:profzoom/macaulay2
sudo apt install macaulay2

Debian

First, run the following:

sudo apt update
sudo apt install ca-certificates debian-keyring

Next, add a line (as root) to the file /etc/apt/sources.list. The particular line is dependent on your version of Debian.

• stable (Debian 13 "trixie")

  deb [signed-by=/usr/share/keyrings/debian-keyring.gpg] https://macaulay2.com/Repositories/Debian trixie/
  

• oldstable (Debian 12 "bookworm")

  deb [signed-by=/usr/share/keyrings/debian-keyring.gpg] https://macaulay2.com/Repositories/Debian bookworm/
  

• oldoldstable (Debian 11 "bullseye")

  deb [signed-by=/usr/share/keyrings/debian-maintainers.gpg] https://macaulay2.com/Repositories/Debian bullseye/
  

Finally, run:

sudo apt update
sudo apt install macaulay2

RPM-based distributions

Fedora, Red Hat Enterprise Linux, and RHEL-compatible distributions like Rocky Linux and AlmaLinux use the dnf package manager.

Fedora

Macaulay2 is available in the official Fedora repositories, and may be installed using the following:

sudo dnf install Macaulay2

The version in the official repositories may be slightly out of date. To obtain the latest version from the Macaulay2 website, save the following as the file /etc/yum.repos.d/Macaulay2.repo as root:

[Macaulay2]
name=Macaulay2 Repository
baseurl=https://macaulay2.com/Repositories/Fedora/$releasever
gpgcheck=0
enabled=1

Then run sudo dnf install Macaulay2.

Red Hat Enterprise Linux

Macaulay2 is not available in the official repositories for RHEL and compatible distributions like Rocky Linux and AlmaLinux. However, packages are hosted on the Macaulay2 website. Save the following as the file /etc/yum.repos.d/Macaulay2.repo as root:

[Macaulay2]
name=Macaulay2 Repository
baseurl=https://macaulay2.com/Repositories/Scientific/$releasever
gpgcheck=0
enabled=1

Then run sudo dnf install Macaulay2.
