Installing TFTP server atftpd in Linux

I need a TFTP server to keep configurations files. I need the server to be simple to setup and be able to send or receive any file without any restrictions. It would be for a lab environment so a strict security is not necessary. I'm using Linux Mint.
In Linux I could find three different TFTP servers: 

• tftpd
• atftpd
• tftpd-hpa

Already tried tftpd see my other post Installing TFTP server in Linux. A minor problem is that you cannot transfer a file to the TFTP server.

Installing atftpd

sudo apt-get install atftpd

Installing TFTP server in Linux

I recently needed a file server to keep boot images and configuration files to be transferred on switches and routers.

I decided to use TFTP because of its simplicity and low memory requirements
