The files in this directory are the architecture dependent Ubuntu distribution files. We hope the automatic procedure described below works for you, so you don't have to download any of these files manually. With luck, you will not have to visit this page again nor read these instructions again. Please let us know if that doesn't work out for you.
(Thanks to Brent Baccala, an Ubuntu distribution for ARM chips is available here. Our test suite has not been run on it.)

Instructions for installing Macaulay2 with root access
Beginning with Ubuntu 21.04 "Hirsute Hippo", Macaulay2 is available in the official repositories and may be installed using:
sudo apt install macaulay2
If your system has an earlier release of Ubuntu or you would like a more recent version of Macaulay2 than is available in the official repositories, then continue reading.
Prepare for installing Macaulay2 (with apt-get, gdebi-gtk, or the Synaptic Package Manager) by adding the following line to the file /etc/apt/sources.list, suitably modified as described in the table below:
deb http://www.math.uiuc.edu/Macaulay2/Repositories/Ubuntu XXXX main
|Operating system||Replacement for XXXX|
(Double check that you have the right replacement for "XXXX" by observing that it appears already on many other lines in that file.)
There are various ways to add that line to that file:
Use the "Synaptic Package Manager", which can be started from the
"System/Administration" menu or the "Desktop/Administration" menu. (You
may also start it with the command "sudo synaptic" in a shell window.)
Pull down the "Settings" menu, and select "Repositories". That will open up
a window called "Software Sources". Now, depending
on which version you have, do one of the following.
- If you see a tab labelled "Other Software" or "Third Party Software", click on it, then click on "Add", and add the entry. If you make a mistake, be prepared to use an editor to edit the file to correct it. If two entries are created, remove or un-check the one corresponding to the source code (since we don't provide those). For "Type", select "Binary", for "URI" insert "http://www.math.uiuc.edu/Macaulay2/Repositories/Ubuntu", for "Distribution" insert the replacement for "XXXX" introduced above, and for "Components" insert "main".
- If you see a tab labelled "Installation Media", then click on it, then click on "Add" and then "Custom", and add the entry.
- Use the "Software Sources" program, which can be started from the "System/Administration" menu, or the "Software Properties" program, which can be started from the "Desktop/Administration" menu.
- Use the command "sudo emacs /etc/apt/sources.list" to edit the file and add that line.
Alternatively, use the following command, as root, (with XXXX replaced, as described
above) to add the line to a separate file where apt-get can find it.
echo 'deb http://www.math.uiuc.edu/Macaulay2/Repositories/Ubuntu XXXX main' >/etc/apt/sources.list.d/macaulay2.listTo get a command shell as root, the following command can be used:
Another thing you should do (now) is to download and save the public key file Macaulay2-key, so you can add it to the key ring used for upgrading the system. This will allow the system to verify the signatures attached to the Macaulay2 distribution files. To add it to the key ring using the graphical user interface, access the "Software Sources" window (or program), as mentioned above, but this time select the "Authentication" tab. Click on the "Import Key File..." button, and select the previously downloaded public key file, Macaulay2-key. To add it to the key ring manually use the command "sudo apt-key add Macaulay2-key".
Another source for the key is from keys.gnupg.net.
Alternatively, the downloading and installation of the key can be accomplished by the following single command
sudo apt-key adv --keyserver hkp://keys.gnupg.net --recv-key CD9C0E09B0C780943A1AD85553F8BD99F40DCB31
Now, using the "Synaptic Package Manager", reload the package lists from the repositories by clicking on the "Reload" button, and then click on the Mathematics (Math) section. You should see "macaulay2" on the list, available for download: click on it. It will add both "macaulay2" and "macaulay2-common" to the list of packages to be installed. (Behind the scenes, the package manager will consult our Ubuntu repository.)
Later upgrades to Macaulay2 will become available to you almost automatically. You can periodically run the Synaptic Package Manager and check for updates by clicking on "Reload" and then on "Mark all Upgrades". Alternatively, when an orange starburst icon is occasionally displayed in your task bar indicating that updates are available from Ubuntu headquarters, you may click on the icon to activate the Update Manager, and then click on "Check" to download any new package information from the software channels, including the Macaulay2 repository. If an update of Macaulay2 is available, it will be displayed at the bottom of the list, after the Important Security Updates and the Recommended Updates, among the Other Updates. Press "Install Updates" to have it installed, along with the others. (If you have not installed the Macaulay2 public key file as described above, then our update will be listed as "Not authenticated", and the "list of changes" will not be available.)
Another way to install Macaulay2, after that line is added to /etc/apt/sources.list, is with these command lines.
sudo apt-get update -q sudo apt-get install -y -q macaulay2
The preferred way to run Macaulay2 is with emacs, but the installation procedure described above doesn't teach emacs how to do that. So, after Macaulay2 is successfully installed as described above, the first thing you should do is to run M2 and to issue the Macaulay2 command setupEmacs(). That will ensure that the next time you start emacs, it knows how to edit *.m2 files, and it knows that when you press the f12 key, it should start Macaulay2 running in an interactive buffer.
If the procedure above doesn't work for you, then you may install the package files manually with dpkg (they all have names of the form *.deb). They come in pairs, one containing the architecture dependent files (in this directory), and one of the the common files containing the architecture independent files and having "common" in the name.
Instructions for installing Macaulay2 without root access
You may install from a tar file, if we have provided one above. Alternatively, here is the procedure for unpacking a *.deb file yourself, which you may use on the two *.deb files mentioned above. (One of them provides the files that depend on the architecture and operating system, and the other provides the files that have the same form in all distrubtions.) We assume the *.deb file is called /tmp/Macaulay2-1.6-AAA-Linux-Ubuntu-XXX.deb, which you have chosen because you have version XXX of Ubuntu. Here "AAA" denotes your computer's architecture.
mkdir foo cd foo ar x /tmp/Macaulay2-1.6-AAA-Linux-Ubuntu-XXX.deb data.tar.gz tar xzf data.tar.gz
The result will be a directory tree named "usr", which can be moved and renamed at will. After moving it, run the program bin/M2 contained within, and run the "setup()" command to set up your standard init files, as described elsewhere. Then the directory "foo" and the file "data.tar.gz" in it can be removed.
Instructions for installing Macaulay2 from Personal Package Archive
An alternate method for installing the latest version of Macaulay2 in Ubuntu is to use the PPA (Personal Package Archive):
sudo add-apt-repository ppa:macaulay2/macaulay2 sudo apt install macaulay2
