¿Cómo actualizar BigBlueButton 2.2 a 2.3 (Ubuntu 16.04 a 18.04)?

En este artículo voy a mostrar un procedimiento para actualizar BigBlueButton  2.2 a 2.3. BigBlueButton 2.2 está usando Ubuntu 16.04 LTS pero BigBlueButton 2.3 necesita Ubuntu 18.04 LTS. Los desarrolladores de BigBlueButton  recomiendan instalar BigBlueButton 2.3 en un servidor Ubuntu 18.04 limpio, pero vamos a actualizar Ubuntu 16.04 a 18.04 siguiendo estos pasos. Esto ahorrará  tiempo  para transferir grabaciones de un servidor a otro servidor. Por favor, tenga en cuenta que debe tomar la copia de seguridad adecuada antes de comenzar. Compruebe algunas de las emocionantes  características de BigBlueButton 2.3. 

sudo apt update && sudo apt upgrade -y && sudo apt dist-upgrade -y && apt autoremove -y
sudo reboot

2) Después de reiniciar el inicio de sesión del servidor de nuevo &ejecutar los siguientes comandos en el terminal. Deberá seguir las instrucciones de la salida. Puede continuar si ve algún paquete que falte de advertencia. La instalación de Ubuntu eliminará / actualizará esos paquetes automáticamente para usted. 

sudo bbb-conf --stop

## main packages
sudo apt purge -yq kurento-media-server nodejs yq bigbluebutton bbb-html5 certbot nginx nginx-common nginx-core

## optional packages but better to remove as BigBlueButton will install those again.
sudo apt purge -yq bbb-apps-akka bbb-apps-screenshare bbb-client bbb-freeswitch-core bbb-fsesl-akka bbb-red5 bbb-transcode-akka bbb-web bbb-record-core kms-core kms-elements mongodb-org mongodb-org-server ffmpeg redis-server openjdk-8-jre openjdk-8-jre-headless

sudo apt auto-remove -y

sudo add-apt-repository --remove ppa:rmescandon/yq -y
sudo add-apt-repository --remove ppa:libreoffice/ppa -y
sudo add-apt-repository --remove ppa:bigbluebutton/support -y
sudo add-apt-repository --remove ppa:certbot/certbot -y

## we'll remove some of the directories. Please take backup if need.
sudo rm -rf /etc/bigbluebutton
sudo rm -rf /usr/local/bigbluebutton
sudo rm -rf /var/log/bigbluebutton
sudo rm -rf /usr/share/bbb-web
sudo rm -rf /usr/share/red5
sudo rm -rf /var/lib/red5
sudo rm -rf /opt/freeswitch
sudo rm -rf /usr/share/etherpad-lite
sudo rm -rf /usr/lib/node_modules
sudo rm -rf /var/lib/mongodb

sudo rm -rf /etc/apt/sources.list.d/*
sudo rm -rf /var/lib/apt/lists/*

sudo mv -f /etc/apt/sources.list /etc/apt/sources.list.tmp

## This is for safety so that won't make conflict with other third party packages. We'll fixed it later.
sudo echo "deb http://archive.ubuntu.com/ubuntu xenial main restricted universe multiverse" > /etc/apt/sources.list

sudo apt clean && sudo apt update -y && sudo apt upgrade -y

sudo apt install -y update-manager-core

sudo do-release-upgrade

3) Si los procedimientos anteriores obtienen éxito &después de reiniciar, debería estar en Ubuntu 18.04 LTS :-). Ahora ejecute los siguientes comandos antes de instalar BigBlueButton 2.3. Puede editar enlaces de repositorio con su réplica favorita.
