Unable to install Postal to VPS

Question

I'm trying to install Postal to my VPS via command:

curl https://raw.githubusercontent.com/atech/postal/master/script/install/ubuntu1604.sh | sh

But face error mentioned below :

Err:8 https://www.rabbitmq.com/debian testing Release 404 OK

E: The repository 'http://www.rabbitmq.com/debian testing Release' does not have a Release file.

N: Updating from such a repository can't be done securely, and is therefore disa bled by default. N: See apt-secure(8) manpage for repository creation and user configuration deta ils.

You can manually add the RabbitMQ repository as described in the website.

This script will include the GPG keys and both the RabbitMQ repository and the Earlang repository.

#!/bin/sh

sudo apt-get install curl gnupg debian-keyring debian-archive-keyring apt-transport-https -y

## Team RabbitMQ's main signing key
sudo apt-key adv --keyserver "hkps://keys.openpgp.org" --recv-keys "0x0A9AF2115F4687BD29803A206B73A36E6026DFCA"
## Launchpad PPA that provides modern Erlang releases
sudo apt-key adv --keyserver "keyserver.ubuntu.com" --recv-keys "F77F1EDA57EBB1CC"
## PackageCloud RabbitMQ repository
sudo apt-key adv --keyserver "keyserver.ubuntu.com" --recv-keys "F6609E60DC62814E"

## Add apt repositories maintained by Team RabbitMQ
sudo tee /etc/apt/sources.list.d/rabbitmq.list <<EOF
## Provides modern Erlang/OTP releases
##
## "bionic" as distribution name should work for any reasonably recent Ubuntu or Debian release.
## See the release to distribution mapping table in RabbitMQ doc guides to learn more.
deb http://ppa.launchpad.net/rabbitmq/rabbitmq-erlang/ubuntu bionic main
deb-src http://ppa.launchpad.net/rabbitmq/rabbitmq-erlang/ubuntu bionic main

After that, don't forget to remove the old and defective entry from the /etc/apt/sources.list, or your apt update will fail.
