Hi guys, go easy on me I’m a Ghost/Digital Ocean newbie 
I’m running Ghost on Digital Ocean and thought I better perform some maintenance, and well I’ve got myself in a spot of trouble!
Message: Unable to update Ghost directly to v4.37.0. You must be on the latest v3.x to update across major versions.
Help: Run “ghost update v3” to get the latest v3.x version, then run “ghost update” to get to v4.
So I ran “ghost update v3” and got this.
ghost-mgr@ghost-ubuntu-s-1vcpu-2gb-lon1-01:/var/www/ghost$ ghost update v3
- sudo systemctl is-active ghost_www-echtalker-com

Downloading and updating Ghost to v3.42.9
A SystemError occurred.
Message: Ghost v3.42.9 is not compatible with the current Node version. Your node version is 16.14.0, but Ghost v3.42.9 requires ^10.13.0 || ^12.10.0 || ^14.15.0
I’ve got a json export and made a copy of the full /var/www/ghost folder.
Thanks in advance
