Como atualizar o BigBlueButton 2.2 para 2.3 (Ubuntu 16.04 para 18.04)?

Neste artigo vou mostrar um procedimento para atualizar o BigBlueButton  2.2 para 2.3. BigBlueButton 2.2 está usando Ubuntu 16.04 LTS, mas o BigBlueButton 2.3 precisa do Ubuntu 18.04 LTS. Os desenvolvedores do BigBlueButton  recomendam instalar o BigBlueButton 2.3 em um servidor Ubuntu 18.04 limpo, mas vamos atualizar o Ubuntu 16.04 para 18.04 seguindo esta etapa. Isso poupará  nosso tempo  para  transferir gravações de um servidor para outro servidor. Por favor, lembre-se de fazer o  backup adequado antes de começar. Confira alguns dos recursos emocionantes do  BigBlueButton 2.3. 

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

2) Depois de reiniciar o login do servidor novamente e executar seguindo comandos no terminal. Você precisará seguir as instruções da saída. Você pode continuar se ver algum pacote faltando aviso. A instalação do Ubuntu removerá/atualizará esses pacotes automaticamente para você. 

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) Se os procedimentos acima obterem sucesso e após a reinicialização, você deve estar no Ubuntu 18.04 LTS :-). Agora execute seguir comandos antes de instalar o BigBlueButton 2.3. Você pode editar links de repositório com seu espelho favorito.
