$ ls -1 /etc/apt/sources.list.d

$ sudo add-apt-repository ppa:oibaf/graphics-drivers

$ ls -1 /etc/apt/sources.list.d
google-chrome.list
google-chrome.list.save
oibaf-ubuntu-graphics-drivers-noble.list

$ cat /etc/apt/sources.list.d/oibaf-ubuntu-graphics-drivers-noble.list
deb http://ppa.launchpad.net/oibaf/graphics-drivers/ubuntu noble main
# deb-src http://ppa.launchpad.net/oibaf/graphics-drivers/ubuntu noble main

Approach II

… as found in the ascii-image-converter github repository's README:
Adding a package source 
echo 'deb [trusted=yes] https://apt.fury.io/ascii-image-converter/ /' | sudo tee /etc/apt/sources.list.d/ascii-image-converter.list
sudo apt update
sudo apt install -y ascii-image-converter
The following command removes the package source (so that the source does not provide any updates anymore): 
sudo rm -v /etc/apt/sources.list.d/ascii-image-converter.list
