Multiple errors at the step : LoRa Server Debian repository

Hi, I am facing a problem during the installation of lora server on my VM. I’m at the step :
“LoRa Server Debian repository” that you can find here :

I did theses 3 commands :

sudo apt-key adv --keyserver --recv-keys 1CE2AFD36DBCCA00
export DISTRIB_ID=lsb_release -si
export DISTRIB_CODENAME=lsb_release -sc
sudo echo “deb${DISTRIB_ID,,} ${DISTRIB_CODENAME} testing” | sudo tee /etc/apt/sources.list.d/loraserver.list

and now when I am executing the last one : sudo apt-get update

here what my screen is showing :

Have you and idea on how I can fix theses errors ?

Thanks :slight_smile:
