Unable to upgrade Ghost due to npm version

[jannis]

I see. You will need to log into your DigitalOcean droplet and update NodeJS there.

I assume you are using the one-click installation there? Then this should work for you:

Update Node (Digital Ocean)

The DigitalOcean one-click App uses nodesource. I recommend updating to Node v10 (v8 is almost end of life) curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash - sudo apt-get install -y nodejs ghost update --force One you’ve updated node, you must run ghost update --force in the ghost directory, this will force Ghost to update its dependencies to match Node v10, otherwise you’ll get more errors.

Replace the setup_10.x with setup_18.x
