Release v21.11.01 updates the version of Node.js to 16.x. Doing this on existing Submitty instances requires the file /etc/apt/sources.list.d/nodesource.list to be manually edited to update the version of Node.js. The current version of Node.js may be determined by running node -v.

The file should be edited to the following:

deb [signed-by=/usr/share/keyrings/nodesource.gpg] https://deb.nodesource.com/node_16.x focal main
deb-src [signed-by=/usr/share/keyrings/nodesource.gpg] https://deb.nodesource.com/node_16.x focal main

Replace focal above with whatever the name of Ubuntu you are running. You can get this information by running lsb_release -cs in the terminal.

After editing the file, the system must be updated by running the following commands:

sudo apt-get update
sudo apt-get upgrade

The new version of Node.js can be verified by running node -v.
