apt-get add new data source

When we add new data:

# vi /etc/apt/sources.list
...
deb http://deb.debian.org/debian stretch main contrib non-free
deb-src http://deb.debian.org/debian stretch main contrib non-free

we got some errors below:

# apt-get update

  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 37BBEE3F7AD95B3F

Fix:

# sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 8B48AD6246925553

If we receive an error likeĀ  below, it looks like you are behind firewall:

Executing: /tmp/apt-key-gpghome.04owBwsfXq/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 8B48AD6246925553
gpg: keyserver receive failed: End of file

Some command to debug:

soft#  gpg -vvv --debug-all --recv-keys --keyserver keyserver.ubuntu.com --recv-keys 8B48AD6246925553
