Ubuntu 12.04 Java Failed Install

[rigel4]

Hi I tried to install Java for Ubuntu 12.04 LTS and the install failed!
I am getting loads of random app crashes and spongy slow response of the system
in general.

I don't know how to remove what's been done or how to actually
get Java on the system.

Everything was good until this. I have copied the terminal
output for you to look at and maybe offer me a way out of this.

Reinstalling is not a good option right now, as i have a ton of data.

Thank you

HI I have solved it myself from a post elsewhere:

sudo rm /var/lib/dpkg/info/oracle-java7-installer* sudo apt-get purge oracle-java7-installer* sudo rm /etc/apt/sources.list.d/*java* sudo apt-get update sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java7-installer

[Helopoh]

I could kiss you.. 2 days of looking and you solved it for me in 3 minutes. Thanks a Bunch!

Rigel / Helopoh,

Please forgive me.. I am not good in Linux.

Expecting your best response ASAP.

Thanks guys, worked perfectly for me.

Try this bsprakash, if you're unsure, one command at a time.

sudo rm /var/lib/dpkg/info/oracle-java7-installer*
sudo apt-get purge oracle-java7-installer*
sudo rm /etc/apt/sources.list.d/*java*
sudo apt-get update
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

Or all in one :

sudo rm /var/lib/dpkg/info/oracle-java7-installer*; sudo apt-get purge oracle-java7-installer*; sudo rm /etc/apt/sources.list.d/*java*; sudo apt-get update; sudo add-apt-repository ppa:webupd8team/java; sudo apt-get update; sudo apt-get install oracle-java7-installer;

Words cannot describe how much I appreciate this fix. I was going absolutely bonkers. I'm a newbie to Ubuntu but I love the vast helpful community it creates. Thanks again!

Following up your CLI, It is workable on my system. Thanks guys ^_~

Oh, man, thank you so much. Spent hours looking at other forums and trying different ideas to install Java. This worked! Thanks.
