I'm trying to install mongodb on ubuntu 15.10. While following this - Install Mongo 3.2 on Ubuntu 15.10 - i got the following error message: 

W: GPG error: http://repo.mongodb.org trusty/mongodb-org/3.2 Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY D68FA50FEA312927

So then I attempted to add the key like this: 

me@devbox:/etc/test$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D68FA50FEA312927

Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --homedir /tmp/tmp.CWnpUGSg5w --no-auto-check-trustdb --trust-model always --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyring /etc/apt/trusted.gpg.d/apt.postgresql.org.gpg --keyring /etc/apt/trusted.gpg.d/nginx_ubuntu_stable.gpg --keyring /etc/apt/trusted.gpg.d/webupd8team_ubuntu_java.gpg --keyserver keyserver.ubuntu.com --recv-keys D68FA50FEA312927
gpg: requesting key EA312927 from hkp server keyserver.ubuntu.com
gpg: keyserver timed out
gpg: keyserver receive failed: keyserver error

Not sure what else to try. I'm currently looking other posts here on this site to see if this has been addressed.

EDIT 1:

Based on this post: Can't add repo keys

I tried to run the command : 

sudo gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys D68FA50FEA312927

and then retried: 

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D68FA50FEA312927

But it's still failing.

Try different keyservers, and try using port 80.

A few servers you could try if keyserver.ubuntu.com doesn't work :

  • keys.gnupg.net (this one worked for me today)
  • pgp.mit.edu
  • sks-keyservers.net
  • keyserver.pgp.com
sudo apt-key adv --keyserver hkp://$pgp_server:80 --recv-keys $wanted_key

2024 year , Mint 21.3 based on 22.04 Problem still exists for any PPA's. Im 2 year use Flatpak for avoid problem with keyserver and it always work for me but it not corrent solving, and take more space on SSD. Every program takes place for its dependencies. Its temporary solution but it works perfectly

sudo add-apt-repository ppa:obsproject/obs-studio sudo apt update sudo apt install obs-studio

Example:: change it to "flatpak install obs" and for run "flatpak run com.obsproject.Studio"

My error log with PPA similar to your error:: gpg: keybox „/etc/apt/keyrings/BC7345F522079769F5BBE987EFC71127F425E228.keyring” utworzony gpg: odbiór z serwera kluczy nie powiódł się: Serwer wskazał niepowodzenie (keyserver always no sends key)
