Installing AWS CLI on Ubuntu gives administrators and automation jobs the aws command before profiles, regions, and service calls can be configured. The current AWS CLI version 2 installer keeps the client independent of older distro or Python packages when scripts need the current major release and a predictable install path.

AWS supports a command line installer for recent 64-bit Linux distributions, including Ubuntu, and provides separate archives for x86_64 and aarch64 systems. The installer places the CLI under /usr/local/aws-cli by default and creates the /usr/local/bin/aws symlink, so checking the active path matters when older APT, pip, or snap copies are already on PATH.

The official snap package is also supported and auto-refreshes, but it does not let teams pin a minor AWS CLI version. The vendor ZIP installer fits repeatable server setup because updates happen only when a new installer is downloaded and run with --update.

Steps to install AWS CLI on Ubuntu:

  1. Open a terminal with sudo privileges.
  2. Refresh the local package index.
    $ sudo apt update
  3. Install the download and extraction tools.
    $ sudo apt install curl unzip ca-certificates

    curl downloads the vendor archive, unzip extracts it, and ca-certificates lets curl validate the AWS HTTPS endpoint on minimal Ubuntu systems.

  4. Check the CPU architecture.
    $ uname -m
    x86_64

    Use the x86_64 AWS CLI archive when this command returns x86_64. Use the aarch64 archive when it returns aarch64.

  5. Download the AWS CLI v2 archive for x86_64 Ubuntu.
    $ curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"

    On aarch64 Ubuntu, use https://awscli.amazonaws.com/awscli-exe-linux-aarch64.zip instead.

  6. Extract the installer directory.
    $ unzip awscliv2.zip
  7. Run the bundled installer.
    $ sudo ./aws/install
    You can now run: /usr/local/bin/aws --version

    The default install directory is /usr/local/aws-cli, and the default symlink path is /usr/local/bin/aws. For an existing manual AWS CLI v2 install, rerun the new installer with sudo ./aws/install --update.

  8. Confirm that the shell resolves the vendor-installed command.
    $ command -v aws
    /usr/local/bin/aws

    If the result is /usr/bin/aws, /snap/bin/aws, or ~/.local/bin/aws, an older install is still earlier on PATH.

  9. Confirm that the active command reports AWS CLI v2.
    $ aws --version
    aws-cli/2.35.3 Python/3.14.5 Linux/6.8.0 exe/x86_64.ubuntu.26

    The exact version, Python runtime, kernel string, and platform suffix change over time. Look for an aws-cli/2.x version line from the intended path.

  10. Run a CLI smoke test before configuring new credentials.
    $ aws configure list
    NAME       : VALUE                    : TYPE             : LOCATION
    profile    : <not set>                : None             : None
    access_key : <not set>                : None             : None
    secret_key : <not set>                : None             : None
    region     : <not set>                : None             : None

    The command should print the configuration table without an error. Existing profiles may show masked access keys or a saved region instead of <not set>. Configure credentials separately before making signed AWS service calls.

  11. Remove the downloaded installer files.
    $ rm -r aws awscliv2.zip

    This cleanup removes only the working directory and archive. It does not remove the installed CLI under /usr/local/aws-cli.
