-## Missing Amazon Linux 2023 repository configuration

-Replication servers use Amazon Linux 2023 (AL2023) and require access to the AL2023 package repository hosted in Amazon S3. If the staging area subnet does not have outbound internet access and the Amazon S3 VPC gateway endpoint policy does not allow access to the AL2023 repository bucket, replication servers may fail to launch or function correctly.
-
-Symptoms of this issue include:
-
-  * Replication stalling or failing after the replication server is launched.
-
-  * Replication server unable to install or update required packages.
-
-
-
-
-To resolve this issue:
-
-  1. Ensure that the Amazon S3 VPC gateway endpoint policy associated with your staging area subnet allows access to the AL2023 package repository bucket (`al2023-repos-<REGION>-de612dc2`). Add the following resource ARN to the endpoint policy:
-    
-        "arn:aws:s3:::al2023-repos-<REGION>-de612dc2/*"
-
-  2. If you use a firewall or proxy, allowlist the following Amazon S3 URL:
-    
-        https://al2023-repos-<REGION>-de612dc2.s3.<REGION>.amazonaws.com/
