A year ago I was running Ubuntu Server 19.04 on rPI4. I needed vcgencmd so I had to install libraspberrypi-bin. I have notes on how to clone the userland repository, edit few files, and compile it from source. I did it last year and it works fine up to this day.
I got another rPI4 today and need to install it again, however it looks like the files in repo changed since and my own obscure method doesn't work any more.
I googled around and following this guide. I've added ppa:ubuntu-raspi2/ppa repo to my fresh Ubuntu 20.04 however after running apt update I get the following error:
root@ubuntu:/tmp# sudo apt update

E: The repository 'http://ppa.launchpad.net/ubuntu-raspi2/ppa/ubuntu focal 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.
It looks like that repo was last updated over 2 years ago I guess this guide is also out of date.
My question in short: how to get libraspberrypi-bin on Ubuntu 20.04 for Raspberry Pi 4?
