Prerequisites

Create an Ubuntu 22.04 LTS instance.

$ cat /etc/issue
Ubuntu 22.04.3 LTS \n \l

Install some prerequisite packages. These packages are included by default in most major distributions of Linux.

$ sudo apt update

$ sudo apt install unzip glibc-source groff less

Installing the CLI

Download the latest AWS CLI zip file.

$ curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"

Extract the downloaded zip file.

$ unzip awscliv2.zip

Run the install program using elevated privileges.

$ sudo ./aws/install --bin-dir /usr/local/bin --install-dir /usr/local/aws-cli

Verify the version of CLI.

$ aws --version
aws-cli/2.13.32 Python/3.11.6 Linux/6.2.0-1012-aws exe/x86_64.ubuntu.22 prompt/off

Updating the CLI

Download the latest AWS CLI zip file. Here we are using the same zip file downloaded earlier.

$ curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"

Extract the downloaded zip file with -u flag. This will automatically update existing files and create new ones as needed.

$ unzip -u awscliv2.zip

Run the install program using elevated privileges with --update flag.

$ sudo ./aws/install --bin-dir /usr/local/bin --install-dir /usr/local/aws-cli --update

Verify the version of CLI.

$ sudo ./aws/install --bin-dir /usr/local/bin --install-dir /usr/local/aws-cli --update
Found same AWS CLI version: /usr/local/aws-cli/v2/2.13.32. Skipping install.
