sudo vim /etc/apt/sources.list.d/java-8-debian.list
and add following content in it.
deb http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main
Now import GPG key on your system for validating packages before installing them.

W: GPG error: http://ppa.launchpad.net/webupd8team/java/ubuntu trusty InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY C2518248EEA14886
E: The repository ‘http://ppa.launchpad.net/webupd8team/java/ubuntu trusty InRelease’ is not signed.
N: Updating from such a repository can’t be done securely, and is therefore disabled by default.
I did exactly as you said and looks like it isn’t much use?…
For all other guys wo see this. If you have debian 8/9/10. On Debian 8 and 9 you can run “apt install openjdk-8-jdk” and for Debian 10 (Buster), if you want the java 8 version add this in the sources.list file in /etc/apt:
deb “http://ftp.debian.org/debian” stretch main
deb-src ” http://ftp.de.debian.org/debian” stretch main
after you add these 2 lines in the sources.list file you have to update with “apt update” and after that you can run “apt install openjdk-8-jdk”. After the installation of java i recommended to delete the 2 lines from the source.list file and update again and now all would be fine
THANK YOU, I was working at this for like 5 HOURS, it took me so long to realize it was Debian 10 and not 9 but if I didn’t see this I would’ve given up THANK YOU!
