Zentyal 3 3 NO PUBKEY error in apt get update

OMG! I have installed Zentyal 3.3 and when I run sudo apt-get update, It work fine but the end of the line, there was an error that

W: GPG error: http://archive.zentyal.org 3.3 Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8E9229F7E23F4777


I have fixed this issue with below commands by adding “archive.zentyal.org".

wget http://keys.zentyal.org/zentyal-3.3-archive.asc

sudo apt-key add zentyal-3.3-archive.asc

sudo apt-get update

Hope this will help you as well, if yes, please show up in comments but please don’t forget to change -3.3 with your Zentyal Version.
