installing docker using apt on ubuntu

remove the snap docker completely

sudo snap remove docker

install docker the right way

sudo apt update

sudo apt install -y ca-certificates curl gnupg lsb-release

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

  

echo \

  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] \

  https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | \

  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

  

sudo apt update

sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

start and enable docker

sudo systemctl start docker

sudo systemctl enable docker

test it

docker run hello-world

here's the one liner script

sudo snap remove docker && \

sudo apt update && \

sudo apt install -y ca-certificates curl gnupg lsb-release && \

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 && \

echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | \

sudo tee /etc/apt/sources.list.d/docker.list > /dev/null && \

sudo apt update && \

sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin && \

sudo systemctl start docker && \

sudo systemctl enable docker && \

sudo docker run hello-world

once done, you should see this at the end:

Hello from Docker!
