Zentyal 3.3 NO PUBKEY error in apt-get update

Zentyal 3.3 NO PUBKEY error in apt-get update is exactly same error which we face in Ubuntu and this is not critical but it required some modification to get updates working. Bad packages sources lists or packages source list which is not resolvable to Debian system is most often considered a major cause of Zentyal update error.

Solution:

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 share it if you consider that helps you or show up in comments but please don’t forget to change -3.3 with your Zentyal Version.
