When will AWS update the Cloud9 Base Images?

Hello, Please find the below information regarding the EOL of Ubuntu AMI:

When will a new Ubuntu base image be available? A new Ubuntu AMI will be available by July 30, 2023.

Can I choose Ubuntu 18.04 after 31 May, 2023? Yes. You can choose Ubuntu 18.04 after 31 May, 2023. The option to choose Ubuntu 18.04 will be available in the console until the next Ubuntu AMI is released.

What happens after the EOL of Ubuntu 18.04? After 31 May, 2023, Ubuntu 18.04 LTS will no longer receive further security updates from Canonical. You can continue to receive security updates by choosing one of the following options:

1. Upgrade to Ubuntu Pro 18.04 with the AWS License Manager. Ubuntu Pro subscription incurs an additional costs.
2. Create a Cloud9 environment with Amazon Linux 2 AMI, or
3. Create an SSH based Cloud9 environment with existing compute with any Linux distribution, which includes Ubuntu 20.04 and Ubuntu 22.04.

Hello,
