Problems Installing Java

[severvip]

I'm having trouble install Java to Ubuntu 8.04. Originally I was getting an error running fakeroot, but I realize I was logged in as root in terminal. So I exited root and I'm still getting errors.

user@my-laptop:~$ cd /home/user

To get myself into my user folder because that is where I have the Java rpm.bin file. Nothing seems to happen when I type that though. I still get this.

user@my-laptop:~$

I guess I'm going to assume I'm in my user folder, even though it doesn't say.

user@my-laptop:/home/user#

Okay so now I type the fakeroot stuff and this is what appears.

user@my-laptop:~$ fakeroot make-jpkg jre-6u6-linux-i586-rpm.bin

Creating temporary directory: /tmp/make-jpkg.yaEGvC9436
Loading plugins: blackdown-j2re.sh blackdown-j2sdk.sh common.sh ibm-j2re.sh ibm-j2sdk.sh j2re.sh j2sdk-doc.sh j2sdk.sh j2se.sh sun-j2re.sh sun-j2sdk-doc.sh sun-j2sdk.sh

Detected Debian build architecture: i386
Detected Debian GNU type: i486-linux-gnu

No matching plugin was found.
Removing temporary directory: done

What am I doing wrong, I can't figure it out. Any help is much appreciated.

Did you try install Java using the repositories with:-

sudo apt-get install sun-java6-jre sun-java6-bin

First, yes you are already in your home directory. That is where you start out every time you open a terminal. You can check this by entering

pwd

That prints the working directory.

Second, Ubuntu does not use RPM. It uses DEB as it's based on Debian. You can very easily install Java as well as a bunch of other goodies like audio codecs and Flash Player by installing the ubuntu-restricted-extras package. You can go Applications→Add/Remove and search for ubuntu-restricted-extras or just paste this in the terminal.

sudo apt-get install ubuntu-restricted-extras

A remark on the above posts: installing ubuntu-restricted-extras will give you an openJDK-based java, while sun-java6-* will give you the 'official' version of sun. The fist one is totally open source and works well 99% of the time, sun's version however turned out to be a lot faster on my machine and may even be more reliable. The choice is yours.

If you install both, you can set the default java with

sudo update-alternatives --config java

It does? Hmmm they must have changed that. I didn't know that. Thanks. I will keep that in mind.
