gpg: recepción del servidor de claves fallida: no name
While I was installing the sdk-2, the second step gave me this error:
gpg: recepción del servidor de claves fallida: no name
After a little research I could work around the error with the following line of code:
$gpg --keyserver keyserver.ubuntu.com --recv 6F3EFCDE
$gpg --export --armor 6F3EFCDE | sudo apt-key add -
$sudo apt-get updateWhere 6F3EFCDE is the key written in the instructions for linux at Intel Real Sense SDK2.
It solved my problem, but I was wondering if someone could explain to me what those lines do, just to understand a little bit more.
Thanks in advance!

I am unfamiliar with use of gpg. My basic understanding though is that these lines get a security key for a server and add it to your 'keyring' of keys. Using sudo apt-get update then refreshes your local package cache, a process that is carried out when you are going to upgrade packages that have already been installed.
The link below provides introductory guidance on the subject of gpg keys.
