Unable to export images - password troubles

Hello there, I might need some advice on exporting images from the content folder in Ghost -

I’m on the self hosted Digitalocean droplet and trying to export my images, following this advice.

The zipping part works fine it seems, but when I try to save to my laptop I get a message "user@’s password: ", then “Permission denied, please try again.”

I’ve tried entering all sorts of passwords - the Ghost one, the droplet one, but to no avail. What might be going on here, has anyone got an idea?

OS: Ubuntu, v20.04.2 LTS
Node Version: v14.17.0
Ghost Version: 3.42.5
Ghost-CLI Version: 1.17.3
