You should not run gpg as root. So try without sudo

gpg --keyserver pgpkeys.mit.edu --recv-key EEA14886

gpg: requesting key EEA14886 from hkp server pgpkeys.mit.edu

gpg: key EEA14886: public key "Launchpad VLC" imported

gpg: no ultimately trusted keys found

gpg: Total number processed: 1

gpg:               imported: 1  (RSA: 1)

Adding key to apt-key:

gpg -a --export EEA14886 | sudo apt-key add -
[sudo] password for arun: 
OK

Verifying key:

apt-key list

 /etc/apt/trusted.gpg
