How to Install GNU Octave in Ubuntu Linux

In this quick tutorial, I show you how to install the latest GNU Octave in Ubuntu Linux. Though Ubuntu software center provides GNU Octave repository, it’s an old version.

There is not any official or unofficial PPA containing latest Octave, but still, you can get this newest software version via a flatpak repository. Flatpak is a universal app repository which can be used across the Linux distros similar to Snap.

Open the Terminal (Ctrl+Alt+T) and run the following command to enable the flatpak framework:

sudo apt-get install flatpak

If you are on older Ubuntu version or Ubuntu 16.04, then you have to run an additional command to get the support of flatpak app.

flatpak remote-add --if-not-exists flathub href="https://flathub.org/repo/flathub.flatpakrepo"https://flathub.org/repo/flathub.flatpakrepo

Now you can go to an official link for installing it.

flatpak uninstall org.octave.Octave

And at last, run the following command to remove the flatpak support from the system:

sudo apt-get remove flatpak
