how do I install java in steamOS???

[Bun]

Hello,
I was wondering how to install Java runtime in SteamOS. I'll be very thankful if anyone can help :)
For the moment I just want to run Multibit

[Robbz]

Open a terminal and type...

sudo apt-get install openjdk-7-jdk openjdk-7-jre icedtea-7-plugin

After this it will ask you for your password.

Enjoy!

Using Add/Remove Software desktop app AKA Nautilus Aptitude gpk-application is an easy way to find package names.

see:

I did everything on the guide, I selected the java packeages from add/remove software, then I tried installung using the commands posted by "Robbz" and I got these errors:

E: Package 'openjdk-7-jdk' has no installation candidate
E: Package 'openjdk-7-jre' has no installation candidate
E: Package 'icedtea-7-plugin' has no installation candidate

Any ideas?

You need to add the Debian package repositories, as Java is not in the SteamOS repositories.

Once the Debian repos are enabled you can use "sudo apt-get install -t wheezy ..." to install the Debian packages.

I found that I needed to install a tzdata-java package from the SteamOS repos first (ie. sudo apt-get install tzdata-java )

[Bun]

I'have already added Debian repos, installed wheezy and tzdata-java and the error persist :/

You're using "sudo apt-get install -t wheezy <packagename>" to install the packages?

[Bun]

Yes
I'm sorry guys I surrender.. I'll move to Linux mint, so testing SteamOS ends for me, I'll test it again in few months :)

[GeeEl]

Ah well, good luck with Mint. I hear good things about Arch, but haven't given it a go yet.
[ EDIT: Note that I've heard that Arch isn't really a beginner distribution ]

Hopefully when SteamOS is getting towards release Valve will add more of the Debian packages directly into the SteamOS repos so we don't have to fiddle around with this guff.

How To Install MultiBit On SteamOS

The instructions for installing multibit are very explicit and easy to follow.
All you have to do is:

1. Go to desktop in SteamOS
2. Download multibit for linux from the instructions on installing multibit website (see Multibit link below)
3. Install java by

   sudo apt-get install openjdk-7-jdk

4. Make the installer executable

   chmod +x multibit-0.5.18-linux.jar

5. Install multibit

   java -jar multibit-0.5.18-linux.jar

6. Follow the Getting Started[multibit.org] instructions.

All this information is found on the MultiBit How to Install[multibit.org] webpage.

I think he's having the same trouble I've been having. Down the dependency tree of openjdk-7-jre are some packages with similar versions in the SteamOS repos and it causes issues. I haven't figured out a way around it yet either.

[Balderick]

When you added wheezy repository to sources.list did you make a preferences file with apt pinning and priorities?
If you did DELETE it.

Following the instruction to install java package as described - apt pulls the necessary dependencies. Simple as. No errors for me.

Here is a list of dependencies that apt installs when i install openjdk-7-jdk

ca-certificates-java icedtea-7-jre-cacao icedtea-7-jre-jamvm java-common
  libatk-wrapper-java libatk-wrapper-java-jni libbonobo2-0 libbonobo2-common
  libgconf2-4 libgif4 libgnome2-0 libgnome2-common libice-dev libidl0
  liborbit2 libpthread-stubs0 libpthread-stubs0-dev libsm-dev libx11-dev
  libx11-doc libxau-dev libxcb1-dev libxdmcp-dev libxt-dev openjdk-7-jre
  openjdk-7-jre-headless openjdk-7-jre-lib ttf-dejavu-extra tzdata-java
  x11proto-core-dev x11proto-input-dev x11proto-kb-dev xorg-sgml-doctools
  xtrans-dev

Here is what my /etc/apt directory contains

desktop@steamos:/etc/apt$ ls -al
total 32
drwxr-xr-x   6 root root 4096 Sep 19 22:54 .

Why would I delete it? It keeps my system from randomly swapping SteamOS specific packages to other versions.

Well if you read the comments in Sharks debian repo thread it is pretty clear indicated Valve updated steamos with a method of controling and protecting sytem packages without any preferences list ;) I suggested in the comments there that Shark edit his very useful thread and after confirming it works for me with out any preferences file. In this particular case it is the difference between a working multibit install or not. Also Directhex (and official announcemets) imply this is not necessary. I tried exactly what is suggested there in the comments.

DELETE the prefernces file and reboot then update,upgrade and follow instruction from MultiBit.

Here is link to the post in the debian repo thread that implies there is absolutely no need for preferences list when adding wheezy repos. http://steamcommunity.com/groups/steamuniverse/discussions/1/648814396114274132/#c648817377347448358 The PROTIP tag is not just grandiose. Directhex is a pro ;)

I have not used a preferences file since15th January for some time. All is well.

If you understand how apt pinning works then feel free to configure your preferences file or simply tell apt what to do so you can work around issues apt is telling you about when you try to install packages from wheezy repo.

Could you link the official announcement you said says this? No offense but I don't know who Directhex is.
