How do I install the Sun Java SDK in Ubuntu 11.10 Oneric?

Question

Since 11.10 Ubuntu does not provide the sun-java-jdk, how do I install it?

Answer 1

Ubuntu 11.10 Oneric

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ferramroberto/java
sudo apt-get update
sudo apt-get install sun-java6-jdk sun-java6-plugin

[Source]

Ubuntu 12.04 Precise

Clean up the historical open jdk:

sudo apt-get purge openjdk*

Add a new repo and install the sdk:

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

If you want the JRE and the browser plugin:

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

Make the sun java the default

You may want to also add the following

sudo update-alternatives --config java

You should get the following

  Selection    Path                                      Priority   Status
------------------------------------------------------------
* 0            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      auto mode
  1            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      manual mode
  2            /usr/lib/jvm/java-6-sun/jre/bin/java       63        manual mode

Press enter to keep the current choice[*], or type selection number: 2

Select (2) and press enter

Now running:

java -version

Returns:

java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) Server VM (build 20.1-b02, mixed mode)

Answer 2

You can install the official package from Oracle :

http://www.oracle.com/technetwork/java/javase/downloads/jdk-7u1-download-513651.html

choose linux as your platform

Answer 3

I'd suggest to go with openjdk if possible (for any average user that is). The only thing you might need from sun/oracle is browser plugin, but that could be installed without installing the jre (just unpack).

Answer 4

There is very good page on official Ubuntu wiki. There you can find all recommended methods. I've used this excellent automatic script.

cd ~/
wget https://raw.github.com/flexiondotorg/oab-java6/master/oab-java6.sh
chmod +x oab-java6.sh
sudo ./oab-java6.sh

Script will build packages from source and place them in local repo, then they can be installed e.g.:

sudo apt-get install sun-java6-jdk sun-java6-fonts sun-java6-source

You can see all available packages in /var/local/oab/deb

Remember to select the right version:

sudo update-alternatives --config java

To setup everything else (like browser plugin, keytool, etc.) you can use this (it will be a long list!):

sudo update-alternatives --all

The script is a wrapper for this Debian script, if you're curious ;)

Answer 5

Upon attempting
$ sudo add-apt-repository ppa:ferramroberto/java
My terminal would hang, not respond to ^C and ultimately (5 min or so) return

Traceback (most recent call last):
  File "/usr/bin/add-apt-repository", line 88, in <module>
    ppa_info = get_ppa_info_from_lp(user, ppa_name)
  File "/usr/lib/python2.7/dist-packages/softwareproperties/ppa.py", line 80, in         get_ppa_info_from_lp
curl.perform()
pycurl.error: (28, 'connect() timed out!')

I resolved this by becoming root, exporting the http/https proxies and then repeating the above line without sudo.
