Step 2 - Adding Webmin repository

sudo add-apt-repository "deb [arch=amd64] http://download.webmin.com/download/repository sarge contrib"
Step 3 - Installing Webmin
Ubuntu now understands where to look for a repository and install a certain application. The command shown below can be used to install Webmin:
sudo apt install webmin -y
In the procedure above, add-apt-repository is used to install external source repositories on Ubuntu 22.04.
Add PPA repository using add-apt-repository command
