Error installing provider "aws": openpgp: signature made by unknown entity,version 0.11.14

Hashicorp have rotated the PGP key they use. Please see the following article:
https://discuss.hashicorp.com/t/terraform-updates-for-hcsec-2021-12/23570

For further reference, you can see in the latest CHANGELOG for v0.11:
https://github.com/hashicorp/terraform/blob/v0.11/CHANGELOG.md#01115-april-26-2021

Unfortunately, you will need to upgrade to version 0.11.15 (Note: There are no deprecations, unless you are using 0.11.2 or earlier.)

Upgrading to 0.11.15 worked for me to. ALso make sure that you update your executable if you are on windows. Otherwise terraform init tries to run a configuration with version 0.11.15 as requirement but only has an older verison to work with

For me, I added the version on the provider and it worked. Here is an example on AWS:

provider "aws" {
  allowed_account_ids = ["${var.allowed_account_id}"]
  profile             = "${var.profile}"
  region              = "${var.region}"
  version             = "~> 2.63"
}

Hope it can help someone without breaking their terraform modules.

Cheers

upgrading to 0.11.15 worked for me

In this article, they are suggesting to upgrade terraform version from 0.11.14 to 0.11.15. We tried to upgrade the terraform version and it worked.
