Error response from daemon: Get "https://registry-1.docker.io/v2/": proxyconnect tcp: dial tcp: lookup proxy.example.com on 8.8.8.8:53: no such host

The error I got:

pegasus@pegasus:~/Downloads/Docker_deb$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": proxyconnect tcp: dial tcp: lookup proxy.example.com on 8.8.8.8:53: no such host.
See 'docker run --help'.

I installed docker using this instructions: enter image description here

But when I use the following command I get error.

pegasus@pegasus:~/Downloads/Docker_deb$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": proxyconnect tcp: dial tcp: lookup proxy.example.com on 8.8.8.8:53: no such host.

Solution

  • My issue was solved by taking the following steps:

    I removed everything related to docker

    for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done

    sudo rm -rf /var/lib/docker/*

sudo apt-get purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras

sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd

    Then installed docker like this:

    # Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

    VERSION_STRING=5:26.1.0-1~ubuntu.24.04~noble
sudo apt-get install docker-ce=$VERSION_STRING docker-ce-cli=$VERSION_STRING containerd.io docker-buildx-plugin docker-compose-plugin

    sudo snap install docker

    docker run hello-world

    N.B. You might need to add your user to docker group.
