To solve the issue, update Ansible. If you are already on the “latest” version of ansible available to for your distro, uninstall, and then install it again following the directions on Ansible’s website

For Ubuntu we can simply do that with

sudo apt remove ansible

sudo apt-add-repository ppa:ansible/ansible

sudo apt install ansible

This version is the same as we previously posted, but adds a security certificate, and lots of extra new stuff! You will need a valid certificate, this is fairly easy to setup using Let’s Encrypt, or you could do a self signed certificate.

Setting up Prerequisite

Installing whisper-ctranslate2

pip install -U whisper-ctranslate2

Install NodeJS

sudo apt install nodejs

or

sudo dnf install nodejs

Install Node Dependencies

npm install formidable
npm install https
npm install fs

Setting up Simple Whisper Web Interface

First we need a web directory to use.

Next lets make an uploads folder

mkdir uploads

Code for main.js. Change WEBSITE.COM to your website name. Node will need access to the certificates. You can run this web app as root (If you do that, then root needs node, and prerequisites), or copy the certs to the users directory, and change the path. If you do the later, look at using a script/cronjob to copy the updated certificates to the users directory.

Run the server with

node main.js

If we want to start it in the background, run

node ./main.js &

Next steps are to setup a SystemD file so we can auto start on system boot and also make the installation quicker/easier.
