fix(utils): differentiate root command error messages for DO

no issue

Fixes an issue for DigitalOcean One-Click installs, that already moved their installation (or are using the updated image) and in both cases have the ghost folder not owned by `root`, where they would be shown the message to follow the 'fix root install' guide, rather than the normal message to not use `root` and switch to the already existing user.
