dockerubuntu-22.04

Ubuntu 22.04 cannot install docker, error during apt-get update

These are the steps that I did:

$ sudo apt-get update
$ sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release
$ sudo mkdir -p /etc/apt/keyrings
$ curl -fsSL https://download.docker.com/linux/debian/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/debian \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

This is the terminal log (the error is here):

$ sudo apt-get update

E: The repository 'https://download.docker.com/linux/debian jammy Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

but if we look at https://download.docker.com/linux/ubuntu/dists/jammy/ it's obviously has the Jammy Release file, i'm not sure what's wrong with it.

Solution

  • Why do you using debian in https://download.docker.com/linux/debian/gpg URL (and echo command)?

    It is should be ubuntu: https://download.docker.com/linux/ubuntu/...

    Please re-check documentation.

    but if we look at https://download.docker.com/linux/ubuntu/dists/jammy/ it's obviously has the Jammy Release file, i'm not sure what's wrong with it.

    Yep, if we look it is .../linux/ubuntu/...
