Can't install MATRIX HAL

Hi, I’m new to the Matrix Creator, so new that I have not even been able to test it because I have not been able to install HAL neither CORE.

Here is what I’ve been doing
(trying to install HAL from package), someone please tell me what I’m doing wrong:

Add the MATRIX repository and packages:
curl -L | sudo apt-key add -
echo “deb $(lsb_release -sc) main” | sudo tee /etc/apt/sources.list.d/matrixlabs.list

% Total % Received % Xferd Average Speed Time Time Time Current

deb bullseye main

Here everything seems to be just fine, then I try this and get:

sudo apt-get update
Hit:1 Index of /debian bullseye InRelease
Hit:3 Index of /raspbian bullseye InRelease
Ign:2 bullseye InRelease
Err:4 bullseye Release
404 Not Found [IP: 443]
Reading package lists… Done
E: The repository ‘ bullseye Release’ does not have a Release file.
N: Updating from such a repository can’t be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Here things are not looking to be going good, since I get a 404 not found error and a repository with no release file.

Then I proceed to upgrade and everything goes just fine.

Now I’m going to try and install the packages and get this:

sudo apt-get install matrixio-creator-init libmatrixio-creator-hal libmatrixio-creator-hal-dev
Reading package lists… Done
Building dependency tree… Done
Reading state information… Done
E: Unable to locate package matrixio-creator-init
E: Unable to locate package libmatrixio-creator-hal
E: Unable to locate package libmatrixio-creator-hal-dev

I’ve been stuck here for a while and don’t know what to do, if anyone knows how to fix this and can help it would mean a lot to me :slight_smile:
