Hey @Hannah,

Thanks for your help, greatly appreciated. 🙂

I ran the commands based on the link you provided, just changed the 14x by 12x and ran `apt purge nodejs` prior the reinstall process to remove my version of node.  
After running the commands, here is the output I have for node (which to me looks fine):

> GhostU@GhostS:/var/www/GhostF$ which node  
> /usr/bin/node  
> GhostU@GhostS:/var/www/GhostF$ node --version  
> v12.21.0  
> GhostU@GhostS:/var/www/GhostF$ /usr/bin/node --version  
> v12.21.0  
> GhostU@GhostS:/var/www/GhostF$ /usr/local/bin/node --version  
> -bash: /usr/local/bin/node: No such file or directory

I ran the update for ghost 4.1.0, which was the version I was already running, with the force flag. However with `ghost start` I end up at the same result as before, and `ghost run` still works as well.
