Install and configure Ubuntu TFTP Server on Ubuntu 20.04 server is very easy, there is no specific requirement needed. As long as your machine have Ubuntu Operating System installed, that's enough to make sure TFTP server will run on it too.
How to Install Ubuntu TFTP Server?
1. Become root
sudo su
enter your user password then enter
You can also use sudo in every command and just need to enter the user password once, but I prefer become root and do everything after it without sudo command. So, the rest of this tutorial, assuming you are doing the same to become root first.
2. Install tftpd-hpa
apt install tftpd-hpa -y

| Install Ubuntu TFTP Server |
Note: make sure you are connected to the internet. If there is an error, try apt update -y to update your application repository database.
3. Edit tftpd-hpa configuration file
nano /etc/default/tftpd-hpa
 |
| Edit tftpd-hpa configuration file |
You only need to add --create to the TFTP_OPTIONS line to be able to upload to TFTP server. And also take a note for TFTP_USERNAME and TFTP_DIRECTORY
4. Change working directory owner
chown tftp:tftp /srv/tftp
This directory is belong to root with nogroup, but TFTP server are working under tftp user and have no permission on that directory. You can either change the folder permission with chmod or change the folder owner and group to tftp (See TFTP_USERNAME line from the configuration file).Make sure the folder owner and group has changed by ls -l /srv command.
5. Restart tftpd-hpa service and make sure it is running and active
systemctl restart tftpd-hpa
then
systemctl status tftpd-hpa
