Unbound Error upon start up

[RobotUser1]

Hi There,

I'm running into an issue after initiating docker-compose up. The QR code will display and it appears that pi-hole and WireGuard are working but unbound is reading a couple errors. The first one states "unbound | standard_init_linux.go:228: exec user process caused: exec format error". The second error that pops up is "unbound | standard_init_linux.go:228: exec user process caused: exec format error and continues infinitely."

Same error here. Here's what I'm seeing on Ubuntu 20.04 on Oracle's free tier ARM VPS:

$ sudo docker-compose up

I did make a couple small changes, but reverting them I still get the same behavior:

This looks like you're on ARM hardware, but the Unbound image isn't made for this architecture. Change it to mvance/unbound-rpi:latest or pedantic/unbound:latest and it should run. Latest versions of Pi-Hole seem to have issues with Unbound anyway, I can no longer resolve DNS locally, it only works when forwarding the requests, but that's another subject.
