sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg# Add the repository to Apt sources:
echo \"deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \"$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
