Oracle Java 7 Installation on Ubuntu 16.04.2 64 Bit

I was trying to install Oracle Java 7 on Ubuntu 16.04.2 64 bit . There are lots of guides on internet but I didn't succeeded. I was getting error "dpkg: error processing package oracle-java7-installer". Finally from lots of search and troubleshooting I was able to install as per following method :-

First cleanup old broken installation:

sudo apt-get purge oracle-java7-installer
sudo rm /etc/apt/sources.list.d/java

Now do manual installation.
Download server-jre-7u80-linux-x64.tar.gz from Oracle Java web site.

wget http://download.oracle.com/otn/java/jdk/7u80-b15/server-jre-7u80-linux-x64.tar.gz

Unzip downloaded package

tar zxvf server-jre-7u80-linux-x64.tar.gz

Move package

mv jdk1.7.0.80/ /opt

Configure java

update-alternatives --install /usr/bin/java java /opt/jdk1.7.0_80/bin/java 1
update-alternatives --install /usr/bin/javac javac /opt/jdk1.7.0_80/bin/javac 1
update-alternatives --set java /opt/jdk1.7.0_80/bin/java
update-alternatives --set javac /opt/jdk1.7.0_80/bin/javac
java -version

That's it, I got working Oracle Java 7 on Ubuntu 16.04.2 64 bit. May be this will help someone else.
