This question already has an answer here:

I'm using Ubuntu 12.04 LTS. I'm trying to install Oracle JDK 7. When I tried to directly download the jdk-7u51-linux-x64.tar.gz from the official website, the download started and after downloading couple of MBs it stopped (you can try it as well, worked the same way for a friend). Using a guide.

led me to

Oracle JDK 7 is NOT installed.
dpkg: error processing oracle-java7-installer (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 oracle-java7-installer
E: Sub-process /usr/bin/dpkg returned an error code (1)

which is normal, as it is downloading from the same link. Exact report here

I tried to download and install the .rpm file. I converted it to deb and installed it. It appears as installed in the Software center, but could not find it via terminal (java -version returns suggestions for installing packages). Image from the Software center here

I tried everything here.

and could not find anything on the internet.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    
What happens if you wget the file, do you get the same behavior where it stops downloading? –  bigbadonk420 Mar 17 at 14:05
    
Yes, the same thing. The response is OK, but downloads just a small part of it: 2014-03-17 15:05:58 (478 MB/s) - `jdk-7u51-linux-x64.tar.gz' saved [5307/5307] When trying to open it, it shows it is corrupted of course. –  Ivaylo Toskov Mar 17 at 14:07
    
Can you run dpkg -L jdk? Also, there is OpenJDK in the main archives and Oracle JDK in an existing PPA. You didn't need to convert an RPM package. –  saiarcot895 Mar 17 at 14:11
    
Almost certainly a server error. It's telling you that the tar.gz is 5307 bytes which is wrong, and I'm getting the same behavior. Two "302 Moved Temporarily" followed by this incorrect file. –  bigbadonk420 Mar 17 at 14:12
    
Did you try the manual method here: askubuntu.com/questions/56104/… –  i08in Mar 17 at 14:49

I suggest you use webup8's PPA. I use it for Java 8, but there's also for Java 7.

See here for Java 7

http://www.webupd8.org/2012/01/install-oracle-java-jdk-7-in-ubuntu-via.html

and here for Java 8 (both can coexist in your system)
