I'm attempting to install JAVA JRE 8. I have tried following the apt-get's, but it cannot be found there. I attempted to download it straight off Oracle's website, and i have the folder now in my /downloads/javajre folder, but I still have JDK7 on my computer and I don't know how to override it. I added the path variable to my ~./bashrc folder, but it still recognizes JDK7 as the main java version. I also tried to apt-get purge JDK7 and it did uninstall, but it is still appearing for java --version. I also tried to locate the environment variable for JDK7 and I can't find it, it is not in /etc/environment. So I'm trying to get the apt-get to work so I can just change the version via change-configuration, but it can't be found.
I also tried this one, but it didn't work:
sudo add-apt-repository ppa:webupd8team/java $ sudo apt-get update $ sudo apt-get install oracle-java8-installer
I need to get this to work. The first is my version, the second is the command and the output.
lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04.4 LTS Release: 14.04 Codename: trusty sudo apt-get install openjdk-8-jre Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package openjdk-8-jre
Any ideas? I've been trying to figure this out for like 4 hours now.
