EC2 Instance Connect is a service that publishes ssh keys for use by EC2 instances based on AWS Credentials. These keys are consumed by on-instance configuration provided by this package. The ssh daemon will query EC2 Instance Metadata service for user-keys at ssh calltime, validate any if present as well as validating their signature, and if all checks pass return will include them in the authorized keys list.
In addition, there is an agent that harvests instance ssh host keys and passes them back to the service. This is for authentication purposes by the EC2 console to open an in-browser ssh terminal connection.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
If you’re running Ubuntu 16.04 LTS (Xenial Xerus) or later, including Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 20.04 LTS (Focal Fossa), you don’t need to do anything. Snap is already installed and ready to go.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install ec2-instance-connect, simply use the following command:
sudo snap install ec2-instance-connect
Browse and find snaps from the convenience of your desktop using the snap store snap.
