Pi-hole or Pihole is a Linux network-level advertisement and Internet tracker blocking application[2][3][4][5] which acts as a DNS sinkhole[6] and optionally a DHCP server, intended for use on a private network.[1] It is designed for low-power embedded devices with network capability, such as the Raspberry Pi,[3][7] but supports any Linux machines.[6][8][9][10]
Pi-hole has the ability to block traditional website advertisements as well as advertisements in unconventional places, such as smart TVs and mobile operating system advertisements.[

In this post, I summarized all necessary steps to set up my home Pi-hole server.
Set up Static IP :
root@hpthin:~# cat /etc/netplan/00-installer-config.yaml
# This is the network config written by 'subiquity'
network:
ethernets:
enp5s0:
addresses: [192.168.2.8/24]
gateway4: 192.168.2.1
nameservers:
addresses: [8.8.8.8, 1.1.1.1]
version: 2
root@hpthin:~#
When editing Yaml files, make sure you follow the YAML code indent standards. If the syntax is not correct, the changes will not be applied.
Once done, save the file and apply the changes by running the following command:
sudo netplan applyUpdate Ubuntu 20.04 8system to latest:

Free Up Port 53, Used By systemd-resolved

/run/systemd/resolve/resolv.conf with /etc/resolv.conf as the destination:sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf
-s is for creating a symbolic and not hard link, and -f is for removing any existing destination files (so it removes /etc/resolv.conf if it exists).3. Reboot your system.
Port 53 should now be free on your Ubuntu system, and you shouldn’t be getting errors like “listen tcp 127.0.0.1:53: bind: address already in use” anymore.
You can check to see if port 53 is in use or not by running
sudo lsof -i :53 – if port 53 is not in use, this command shouldn’t show any output.Install Docker, Docker-Compose and Portainer
