Answer 1

There is a way to install jdk7 on Ubuntu 12.10 in this page http://www.upubuntu.com/2012/10/how-to-install-oracle-java-7-jre-7-jdk.html

I tried to install and I have installed correctly.

Answer 2

Take a look here Unixmen.com

Or if you prefer:

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java7-installer

That's all.

Answer 3

It did not work for me too. It seems, that the download url of the oracle java package is changed, or they require to log in for the download.

This is how I have solved the problem:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

This gives "302 Moved Temporarily" and "sha256sum mismatch jdk-7u51-linux-x64.tar.gz" error, so download the package manually from here (you need to log in): http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html and overwrite with the downloaded file in this directory /var/cache/oracle-jdk6-installer

Then repeat the last command again, and now it will work:

sudo apt-get install oracle-java7-installer

This is an old post, but in case you stumble over this problem currently you are probably running into the problem that you're not on one of the LTS releases.

If you go to https://launchpad.net/~webupd8team/+archive/java/+packages you'll see for which series these packages are published, atm it's:

• Lucid (10.04)
• Precise (12.04)
• Saucy (13.10)
• Trusty (14.04)
• Utopic (14.10)

for the oracle-java7-installer - 7u55-0~webupd8~1

Now check with

lsb_release -a

which version you're on. For me it was raring (13.04) and as you can see above it's not published for this any more. So after the

sudo add-apt-repository ppa:webupd8team/java

I went to /etc/apt/sources.list.d/webupd8team-java-raring.list and /etc/apt/sources.list.d/webupd8team-java-raring.list.save and changed the raring to saucy, so the entries look like

deb http://ppa.launchpad.net/webupd8team/java/ubuntu saucy main

I then ran

sudo apt-get update

and after that I could install the package

sudo apt-get install oracle-java7-installer
