Here are my notes to install yarn and upgrade an unsupported Node to v8
The general problem, on bench update or bench start this warning:
11:34:01 watch.1 | warning You are using Node “7.10.0” which is not supported and may encounter bugs or unexpected behavior. Yarn supports the following semver range: “^4.8.0 || ^5.7.0 || ^6.2.2 || >=8.0.0”
Somehow I installed node v0.10.25 and had install yarn but got this CERT_UNTRUSTED error:
frappe@erpnext:~/frappe-bench$ sudo npm install -g yarn

This fixed the above:
frappe@erpnext:~/frappe-bench$ npm config set registry=“http://registry.npmjs.org/”

Now install yarn:
frappe@erpnext:~/frappe-bench$ sudo npm install -g yarn
npm http GET http://registry.npmjs.org/yarn
npm http 200 http://registry.npmjs.org/yarn
npm http GET http://registry.npmjs.org/yarn/-/yarn-1.16.0.tgz
npm http 200 http://registry.npmjs.org/yarn/-/yarn-1.16.0.tgz
npm WARN engine yarn@1.16.0: wanted: {"node":">=4.0.0"} (current: {"node":"v0.10.25","npm":"1.3.10"})
frappe@erpnext:~/frappe-bench$ node -v
v0.10.25
Next install Node 8.x with this:
frappe@erpnext:~/frappe-bench$ curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
## Installing the NodeSource Node.js 8.x LTS Carbon repo...
## Run `sudo apt-get install -y nodejs` to install Node.js 8.x LTS Carbon and npm
## You may also need development tools to build native addons:
sudo apt-get install gcc g++ make
## To install the Yarn package manager, run:
curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt-get update && sudo apt-get install yarn
frappe@erpnext:~/frappe-bench$ sudo apt-get install -y nodejs
frappe@erpnext:~/frappe-bench$ node -v
v8.16.0
And finally run bench setup requirements --node
