LightZone v4.1.2 now available

This is for the sake of the project as a whole.

Masahiro has today uploaded v4.1.2 for Windows, with Linux and Mac to follow.  See his forum post here.  Changelog here.

My update manager pops up an error when it tries to update to ver. 4.1.2 ..... " Requires installation of untrusted packages.

The action woul require the installation of packages from not authenticated sources."

Untrusted packages

Try with


sudo apt-get install --allow-unauthenticated lightzone


Are you sure you imported the key as described in the download for ubuntu? 


Hope this helps

libgomp missing

Have downloaded Lightzone 4.1.2, and, when I open it, I get an error message which says:


Couldn't link with native library: "DCRaw

/usr/lib/lightzone/`/usr/lib/x86_64-linux-gnu/  version `GOMP_4.0' not found

(required by /usr/lib/lightzone/


Lightzone then opens, but displays symptoms which may indicate the lack of libgomp

(for example, it keeps complaining about the lack of image metadata). This bug has been there since 4.1 or so.
