gpg --keyserver keyserver.ubuntu.com --recv 3E5C1192
gpg --export --armor 3E5C1192 | sudo apt-key add -
sudo apt-get update
gpg --keyserver keyserver.ubuntu.com --recv 3E5C1192 gpg --export --armor 3E5C1192 | sudo apt-key add - sudo apt-get update
gpg --keyserver keyserver.ubuntu.com --recv 3E5C1192
