Installing java 8:update-alternatives: error: alternative path /usr/lib/jvm/jdk1.8.0/bin/java doesn't exist
I know this question might seem like a duplicate question, but I think its not. I'm trying to install java 8 on my ubuntu 14.04 LTS. I have tried many methods, but nothing worked for me. So I downloaded jre-8u25-linux-x64.tar.gz. Then I did the following:
tar -xvf jre-8u25-linux-x64.tar.gz
sudo mkdir -p /usr/lib/jvm
sudo mv ./jdk1.8.0_25/ /usr/lib/jvm
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0/bin/java" 1but I got the following error :
update-alternatives: error: alternative path /usr/lib/jvm/jdk/bin/java doesn't exist`When I opened jdk1.8.0_25 I didn't find bin/java in it, so I re-downloaded it, but the same problem occurred.
Can anyone tell me what I'm doing wrong here?
EDIT:
The output of : update-alternatives --display java

After you execute sudo mv ./jdk1.8.0_25/ /usr/lib/jvm, is the folder, /usr/lib/jvm/jdk1.8.0_25 created or /usr/lib/jvm/jdk1.8.0 created?
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/**jdk1.8.0**/bin/java" 1From the below link :
update-alternatives --install /usr/bin/javac javac /opt/jdk/jdk1.8.0_05/bin/javac 100I had a folder /usr/lib/java-8-openjdk-amd64, so I made a symbolic link to it and named it java-8-oracle. It worked.
