Right now I am using Ubuntu 18.04 beta 2 (Bionic) and already change the repository to kartolo sby to upgrade my Ubuntu, but when I run this command :
I also already do :
sudo apt-get update, sudo apt-get upgrade sudo do-release-upgrade or sudo do-release-upgrade -d
and change the setting of software and update to find new release of Ubuntu and it's still show message that no new release of Ubuntu.
How can I upgrade my beta version to final release version ?
