Updating AWS CLI on Ubuntu 14.04

I installed awscli on my EC2 instance using apt-get install.

The version is still aws-cli/1.2.9 and no longer updates if I use apt-get upgrade awscli. The latest release from what I Googled is 1.10.30.

How can you update aws cli on Ubuntu 14.04?

Thank you.

PS. Other than using pip since I don't have that.

Here's the explanation on how you can perform the upgrade.

Here's what did the job for me:

To install the AWS CLI using the bundled installer
Download the AWS CLI Bundled Installer using wget or curl.
Unzip the package.

Run the install executable.

On Linux and OS X, here are the three commands that correspond to each step:

curl "https://s3.amazonaws.com/aws-cli/awscli-bundle.zip" -o "awscli-bundle.zip"
unzip awscli-bundle.zip
sudo ./awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws
