Solution

You just need to install the dirmngr package on your system. Simply execute the following commands on terminal to install:

sudo apt update
sudo apt install dirmngr --install-recommends

After installing dirmngr package, again tried to import the GnuPG key and successfully imported it to our Debian system.
