Hi,
on Ubuntu 14.04, when attempting to install the EE stack I receive an unable to install updates message. After a sudo apt-get update it shows the following:
GPG error: http://mirror.aarnet.edu.au trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY CBCB082A1BB943DB
When trying to add the key manually with:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys CBCB082A1BB943DB
the keyserver timed-out:
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --homedir /tmp/tmp.9oFSalfYMh --no-auto-check-trustdb --trust-model always --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyring /etc/apt/trusted.gpg.d/ondrej-php5.gpg --keyring /etc/apt/trusted.gpg.d/rtcamp-nginx.gpg --keyserver keyserver.ubuntu.com --recv-keys CBCB082A1BB943DB
gpg: requesting key 1BB943DB from hkp server keyserver.ubuntu.com
gpg: keyserver timed out
gpg: keyserver receive failed: keyserver error
Any advice?
