If you got this message « bbb-install did not detect node js 16.x candidate for installation » when you try to install bigbluebutton you should check your node js version using this command:
node -v
if your version is minor than 16 you should install a 16 version of node:
- install your PPA in order to install node
cd ~
curl -sL https://deb.nodesource.com/setup_16.x | sudo bash -
if you dont have curl you should add it by :
sudo apt install curl
2. install node js from new repo
sudo apt -y install nodejs
3. check node installed version
node -v
v16.14.2
now you can continue installing bigbluebutton ^^
