PPA for Ubuntu now available

Posting rules: It shouldn't need saying, but... play nice. Please keep your discussions civil. You can disagree, just don't be disagreeable. And, of course, all of the usual stuff like no spamming. Tex adds: I'll be rigorously enforcing this as we go along. We're probably going to be a small community in a little lifeboat, so we can't have members at each others' throats. This is for the sake of the project as a whole. So when you post, pretend you're speaking in person with your very wealthy auntie who has always treated you wonderfully and currently lists you prominently in her will. I won't be tossing anyone out of the forums because we are all in this together (except spammers: immediate membership cancelation), but I'll delete suspect posts right away.

PPA for Ubuntu now available

Hello Ubuntu/Mint Linux users,


Because current OBS (OpenSuse Build Service) won't build packages for 16.04 LTS, I created a "LightZone team" on Launchpad and released a PPA (Private Package Archive) today:


You can get packages for Xenial (16.04), Wily (15.10), Trusty (14.04), and Precise (12.04) via this PPA.


If you are not sure how to install softwares from PPA, please refer an instruction on Launchpad Help:


Alternatively, you can use software-center GUI:

  Software Center > Edit > Software Sources... > Other Software > Add...


I'm going to keep the older OBS repositories, but if the PPA works fine for you, it is a good idea to remove the older apt-line:

  sudo rm /etc/apt/sources.list.d/lightzone.list



Thank you

Thank you for the update for Ubuntu 16.04 :) Was searching for this.

Java Errors

Following a Java upgrade on my Ubuntu 12.04 lightzone would not open.  So I purged it and added the ppa.

Lightzone failed to start, with the following error messages:

Can someone please point me in the right direction (upgrading Ubuntu 12.04 LTS is NOT an option).





Update java runtime

I'm not sure the cause of this, but the java version "1.6.0_39" is not an updated one. Install "openjdk-7-jre", then set it as a default java using "sudo update-alternative --config java" command.



Update java runtime

It turns out that openjdk-7-jre had been installed but version 6 had been set as the default.

Running sudo update-alternatives --config java [Note alternatives with an "s"] did the trick.

Thank you, Masahiro
