Failed to install supervisor docker container in Raspbian/Debian

Hi, I’m trying to install the HassIO in Raspbian by following all the steps mentioned in official guide. I have successfully execute all steps and when i install the HassIO by executing the following script,

curl -sL "https://raw.githubusercontent.com/home-assistant/hassio-installer/master/hassio_install.sh" | bash -s -- -m raspberrypi3

The installation stuck during installation of the supervisor docker with following message and i have no clue what is the root cause and the fix for that.

[Info] Install supervisor Docker container
