+Note: To solve DNS port 53 error 
+-------------------------------------------------------------------
+Port 53 is being used at your host machine, that's why you can not bind 53 to host.
+
+To find what is using port 53 you can do: sudo lsof -i -P -n | grep LISTEN
+
+I'm a 99.9% sure that systemd-resolved is what is listening to port 53. To solve that you need to disable it. You can do that with these 2 commands:
+
+    systemctl disable systemd-resolved.service
+    systemctl stop systemd-resolved
+
+Now you have port 53 open, but no dns configured for your host. To fix that, you need to edit '/etc/resolv.conf' and add the dns address. This is an example with a common dns address:
+
+nameserver 8.8.8.8
+
+If you have another nameserver in that file, I would comment it to prevent issues.
+Once pihole docker container gets running, you can change the dns server of your host to localhost, as you are binding port 53 to the host machine. Change again '/etc/resolv.conf' like this
+
+nameserver 127.0.0.1
+
+Hope this helped! ( I recommend you to learn docker-compose, it is easier to use than 'docker run' IMO)
