It's been a week now, that Debian Bullseye has been released, and exadrums packages are part of it!

If you use Debian, and have upgraded to Bullseye, you can now install exadrums via apt:

sudo apt install exadrums

What about Raspberry Pi OS?

It's only been a few days since Debian 11 has been released, so there's no news about the next Raspberry Pi OS (formerly Raspbian). Let's give them some time to publish a proper release. I can already tell you that you'll get the same version of exadrums as Debian in Raspberry Pi OS, it'll be exadrums 0.6.0.

Anyhow, when the new Raspberry Pi OS will be released, you'll be able to install exadrums via apt on your Raspberry Pi.

Using Debian Bullseye on a Raspberry Pi

If you don't want to wait until the version of Raspberry Pi OS comes out, you can install Debian Bullseye on your Raspberry Pi using one of the images available at: Tested images. I haven't tried any of them, but they've been tested, so they should work.
