Somehow I'm getting this
unbound-checkconf[1117:0] fatal error: interface: 127.0.0.1 present twice, cannot bind same ports twice.
Previously had unbound working without issue.
Difference being that up until now I've always used the guide at https://docs.pi-hole.net/guides/dns/unbound/
Upon reinstalliung Dietpi I realised there was an autoinstaller so used that... (no prior installation)
Is it fixable or would I be easier just nuking unbound from dietpi (uninstall) and start again ?
Edit;- Uninstall/reinstall fixed issue. I THINK it was because I'd tried to install concurrently with Pihole.... set pihole up first and it is fine. I also didn't have "apt-utils" installed as a dependency - that delayed the install so it didn't work properly.... plus I may have also ran installer twice

Yeah my fault. I can delete this if you like....
