Hello, new Debian user here.
apt-get install default-jre
gives me the by now old version 7 java,
apt-get install openjdk-8-jre
produces ‘E: Unable to locate package openjdk-8-jre’
How do I upgrade to the current openjdk?
It seems to be available in jessie-backports ( https://packages.debian.org/search?keywords=openjdk-8-jre )
