    Hi all, I have a similar issue as @languille11, and want people to know that this issue is not specific to him.

    I already installed the kernel from aaeon-cm/5.4-upboard/ubuntu, and when I run

    sudo apt update

    I get the following:

    Hit:1 http://packages.ros.org/ros2/ubuntu focal InRelease
    Hit:2 http://archive.ubuntu.com/ubuntu focal InRelease
    Hit:3 http://archive.ubuntu.com/ubuntu focal-updates InRelease

    E: The repository 'http://ppa.launchpad.net/aaeon-cm/5.4-upboard/ubuntu focal Release' no longer has a Release file.
    N: Updating from such a repository can't be done securely, and is therefore disabled by default.

    I hope this helps.

    @DCleri could you help? The instructions provided here seem outdated. Where can we get the latest kernel for the UP boards? All the related repositories and packages hosted on Launchpad are no longer accessible.
    Thank you!

    Can confirm that this is a problem here and will be impacting all Amber Robotics customers using the B1 robot arm. In my case, I am gettng a 403 error:

    ~$ sudo apt-get update
    Hit:1 http://ppa.launchpad.net/nemh/systemback/ubuntu xenial InRelease
    Err:2 http://ppa.launchpad.net/aaeon-cm/5.4-upboard/ubuntu focal InRelease

    I, too, am having this same issue. A few days ago I was getting the 404 Not found error, and now today am receiving the 403 forbidden response.
