Installation Error and Suggested Resolution

[zuluana]

I received the following error while attempting to use the linked S3 template:

deb https://packagecloud.io/dokku/dokku/ubuntu/ trusty main
Aug 12 15:57:06  cloud-init[1332]: W: GPG error: https://packagecloud.io/dokku/dokku/ubuntu trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY
Aug 12 15:57:06 cloud-init[1332]: W: The repository 'https://packagecloud.io/dokku/dokku/ubuntu trusty InRelease' is not signed.

To solve this, I upgraded to the most recent version of Dokku by changing the DokkuVersion parameter to v0.25.0 and updating to a supported version of Ubuntu by changing the image in the template:

    "Mappings": {
        "RegionMap": {
            "us-east-1": {
                "AMI": "ami-06cdbd80022d89537"
            },
            "us-east-2": {
                "AMI": "ami-09862fadec6997084"
            },
        }
    }

These AMIs can be found here: https://cloud-images.ubuntu.com/locator/ec2/

Thanks for the package @tobiasmcnulty this saved quite a bit of time =)
