Unable to locate package swagger

[emaborsa]

As written here , I am trying to install swagger using the following command:

sudo apt install -y apt-transport-https gnupg curl
curl -1sLf 'https://dl.cloudsmith.io/public/go-swagger/go-swagger/gpg.2F8CB673971B5C9E.key' | sudo apt-key add -
curl -1sLf 'https://dl.cloudsmith.io/public/go-swagger/go-swagger/config.deb.txt?distro=debian&codename=any-version' | sudo tee /etc/apt/sources.list.d/go-swagger-go-swagger.list
sudo apt update 
sudo apt install swagger

What I get is Unable to locate package swagger, maybe because of:

E: The repository 'https://dl.cloudsmith.io/public/go-swagger/go-swagger/deb/debian any-version InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

I am working on Ubuntu 20.04LTS on Windows WSL.
