I am on UBUNTU. JDK version currently installed is:

java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

the configuration being installed is:

sudo update-alternatives --config java
There is only one alternative in link group java 
(providing /usr/bin/java):     /usr/lib/jvm/java-7-oracle/jre/bin/java

I downloaded the latest tar.gz archive of JDK 1.8.

How can I easily install JDK 1.8 from tar.gz overriding/uninstalling the JDK 1.7 currently installed? Or even without explicitly use the tar.gz.

This is what I do on debian - I suspect it should work on ubuntu (amend the version as required + adapt the folder where you want to copy the JDK files as you wish, I'm using /opt/jdk):

wget --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u71-b15/jdk-8u71-linux-x64.tar.gz
sudo mkdir /opt/jdk
sudo tar -zxf jdk-8u71-linux-x64.tar.gz -C /opt/jdk/
rm jdk-8u71-linux-x64.tar.gz

Then update-alternatives:

sudo update-alternatives --install /usr/bin/java java /opt/jdk/jdk1.8.0_71/bin/java 1
sudo update-alternatives --install /usr/bin/javac javac /opt/jdk/jdk1.8.0_71/bin/javac 1

Select the number corresponding to the /opt/jdk/jdk1.8.0_71/bin/java when running the following commands:

sudo update-alternatives --config java
sudo update-alternatives --config javac

Finally, verify that the correct version is selected:

java -version
javac -version

Newer jdk, 8u60, found at: http://download.oracle.com/otn-pub/java/jdk/8u60-b27/jdk-8u60-linux-x64.tar.gz Note that this will not work without the cookie set, so use wget as in the answer.
Thanks. In my case it was already installed but just not the default. sudo update-alternatives --config javac was then enough.
How do you remove the older versions safely after install the newer version?
Java 9 is gonna release shortly . just for extra information though : )
Update: the url gives a 404. Still, one could just download tar file and follow the rest of the instructions.

Just use these command lines:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

If needed, you can also follow this Ubuntu tutorial.

The java 8 installer seems to require interaction to agree to their TOS, even with apt-get install -y... Is there any way to force it to agree from the command line so that this can be automated, e.g. in Vagrant?
When your system is behind a proxy, use 'sudo -E' to preserve environment, and make sure appropriate proxy env's are configured.
Package 'oracle-java8-installer' has no installation candidate

Add the repository and update apt-get:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update

Install Java8 and set it as default:

sudo apt-get install oracle-java8-set-default

Check version:

java -version

You can easily install 1.8 via PPA. Which can be done by:

$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java8-installer

Then check the running version:

$ java -version

If you must do it manually there's already an answer for that on AskUbuntu here.

Can you tell me specifically which command failed? The first one?
The second one... lots of messages like these: W: Failed to fetch it.archive.ubuntu.com/ubuntu/dists/saucy-backports/restricted/… 404 Not Found [IP:...
Are you using an LTS release of Ubuntu?
Ubuntu 13.10 is end-of-live and has been since July of 2014. Maybe they left the packages on the server for a while, but they are gone now. The best thing to do is installing a supported release of Ubuntu. Or if you don't want to upgrade you'll need to attempt a manual installation like I liked in the original answer.

You can do the following to install java 8 on your machine. First get the link of tar that you want to install. You can do this by:

  1. go to java downloads page and find the appropriate download.
  2. Accept the license agreement and download it.
  3. In the download page in your browser right click and copy link address.

Then in your terminal:

$ cd /tmp
$ wget http://download.oracle.com/otn-pub/java/jdk/8u74-b02/jdk-8u74-linux-x64.tar.gz\?AuthParam\=1458001079_a6c78c74b34d63befd53037da604746c
$ tar xzf jdk-8u74-linux-x64.tar.gz?AuthParam=1458001079_a6c78c74b34d63befd53037da604746c
$ sudo mv jdk1.8.0_74 /opt
$ cd /opt/jdk1.8.0_74/
$ sudo update-alternatives --install /usr/bin/java java /opt/jdk1.8.0_91/bin/java 2
$ sudo update-alternatives --config java // select version
$ sudo update-alternatives --install /usr/bin/jar jar /opt/jdk1.8.0_91/bin/jar 2
$ sudo update-alternatives --install /usr/bin/javac javac /opt/jdk1.8.0_91/bin/javac 2
$ sudo update-alternatives --set jar /opt/jdk1.8.0_91/bin/jar
$ sudo update-alternatives --set javac /opt/jdk1.8.0_74/bin/javac
$ java -version // you should have the updated java

Most of the answers for this question can not helped me in 2020.

This notification from download site of Oracle may be the reason:

Important Oracle JDK License Update

The Oracle JDK License has changed for releases starting April 16, 2019.

I try to google a little bit and those tutorials below helped me a lot.

  1. Remove completely the previous version of JVM installed on your PC. 

    sudo update-alternatives --remove-all java
sudo update-alternatives --remove-all javac
sudo update-alternatives --remove-all javaws

# /usr/lib/jvm/jdk1.7.0 is the path you installed the previous version of JVM on your PC
sudo rm -rf /usr/lib/jvm/jdk1.7.0

    Check to see whether java is uninstalled or not

    java -version

  2. Install Java 8 JDK.

    • Download Java 8 from Oracle's website. The version being used is 1.8.0_251. Pay attention to this value, you may need it to edit commands in this answer when Java 8 is upgraded to another version.
    • Extract the compressed file to the place where you want to install.

    cd /usr/lib/jvm
sudo tar xzf ~/Downloads/jdk-8u251-linux-x64.tar.gz
    • Edit environment file

    sudo gedit /etc/environment
    • Edit the PATH's value by appending the string below to the current value

    :/usr/lib/jvm/jdk1.8.0_251/bin:/usr/lib/jvm/jdk1.8.0_251/jre/bin
    • Append those strings to the environment file

    J2SDKDIR="/usr/lib/jvm/jdk1.8.0_251"
J2REDIR="/usr/lib/jvm/jdk1.8.0_251/jre"
JAVA_HOME="/usr/lib/jvm/jdk1.8.0_251"
    • Complete the installation by running commands below

    sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0_251/bin/java" 0
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.8.0_251/bin/javac" 0
sudo update-alternatives --set java /usr/lib/jvm/jdk1.8.0_251/bin/java
sudo update-alternatives --set javac /usr/lib/jvm/jdk1.8.0_251/bin/javac

update-alternatives --list java
update-alternatives --list javac
