The issue I am facing:
Pihole FTL uses port 53
conflicts with port of unbound dns server
Details about my system:
Ubuntu 20.01
What I have changed since installing Pi-hole:
nothing
Please consider working through Pi-hole's guide on setting up unbound, where using port 5335 is suggested.

I have but I do not know where is this 8953 port is coming from
tcp 0 0 127.0.0.1:5335 0.0.0.0:* LISTEN 14540/unbound
tcp 0 0 127.0.0.1:8953 0.0.0.0:* LISTEN 14540/unbound
tcp6 0 0 :::53 :::* LISTEN 2365/docker-proxy
from unbound.conf manual
control-port: <port number>
The port number to listen on for IPv4 or IPv6 control interfaces,
default is 8953. If you change this and permissions have been
dropped, you must restart the server for the change to take
effect.
Unbound control uses that port.
I removed 8953 from control-port but still I am getting 8953 in netstat result.
what other config I should look at ?
UPDATE:
on the other osbox running unbound too has unbound control running with port 8953 but thats not erroring.
only rockpi is having these errors.

As mentioned by mibere and jfb, Port 8953 is used by unbound itself as its standard port for remote controlling it via unbound-control. It would not interfere with normal DNS resolution.
You are likely observing port 8953 in your configuraton because you were trying to reproduce For unbound users: add remote control to your configuration - #4 by vitachaos, and unsuccessfully so, judging by your most recent posts.
Users in this forum are ususally more than willing to help, but you're making that all the more difficult if you spread your problems and configurations over several posts. It's hard to get a complete picture that way.
Also, your original question - what port you should use for unbound when working with Pi-hole - has been answered already.
As it is not necessary to enable remote control in order for unbound to cooperate with Pi-hole, I'd recommend to revert your changes, or better: start from a clean slate.
Following the guide I've posted earlier will lead to a working installation within minutes.
For your issues with remote-controlling unbound, I'd recommend continuing the discussion in the related post, or open a new topic altogether.
