The issue is when connecting with Packer to the instance with SSH, we face removal of ssh-rsa from PubKeyAcceptedTypes:
RSA-2048 keys do still work in general, as long as your SSH client is using sha256 signatures
The issue is that the Go library used by Packer (and others) does not.
OpenSSH migrated the ssh-rsa key type, which historically used the ssh-rsa signature algorithm based on SHA-1, to the new rsa-sha2-256 and rsa-sha2-512 signature algorithms. (Golang issues: golang/go#49952)
Packer SDK PR : hashicorp/packer-plugin-sdk#107
So we need to bump packer sdk version to use this fix
