@Stephen_F Thanks for pointing that out. I have updated the install script but it’s not working just now. I’ll have to look into that at the beginning of next week.
Till then, please execute the following commands to switch over:
sudo su
systemctl stop openhab2.service
apt purge oracle-java8-jdk
cat <<EOT >> /etc/apt/sources.list.d/webupd8team-java.list
deb http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main
deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main
EOT
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys EEA14886
apt update
apt -y install oracle-java8-installer
apt -y install oracle-java8-set-default
systemctl start openhab2.service
