   mkdir -p /etc/apt/keyrings

2. Download the GPG key:

   curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg

3. Add the Node.js 22 repository:

   echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_22.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list
