LUA Script Option disappear after updating to 3.8

It was disabled at build time. You will need to get a package that has it enabled and install that. There is nothing else you can do locally, unless you build the software yourself.

See the new version from @darix, it worked for @rvietor.

Thank You All for your help
Problem solved.

apt remove darktable

echo 'deb [http://download.opensuse.org/repositories/graphics:/darktable/xUbuntu_20.04/](http://download.opensuse.org/repositories/graphics:/darktable/xUbuntu_20.04/) /' | sudo tee /etc/apt/sources.list.d/graphics:darktable.list
curl -fsSL [https://download.opensuse.org/repositories/graphics:darktable/xUbuntu_20.04/Release.key](https://download.opensuse.org/repositories/graphics:darktable/xUbuntu_20.04/Release.key) | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/graphics_darktable.gpg > /dev/null
sudo apt update
sudo apt install darktable

Previously was using that repo
deb [http://ppa.launchpad.net/ubuntuhandbook1/darktable/ubuntu](http://ppa.launchpad.net/ubuntuhandbook1/darktable/ubuntu) focal main

The package at this site seem to be compile without LUA
 [https://launchpad.net/~ubuntuhandbook1/+archive/ubuntu/darktable](https://launchpad.net/~ubuntuhandbook1/+archive/ubuntu/darktable)

I have the same problem described here (LinuxMint 20.02, Ubuntu 20.04, no LUA in DT after darktable 3.8 installation) and tried to solve it .
If I understand right, the first 5 code lines of @jadupl2 last post should install a DT build with LUA support. I’m not so familiar with these Linux commands. I have an idea what they are doing but I get an error executing the command below and can’t identify the reason.

curl -fsSL https://download.opensuse.org/repositories/graphics:darktable/xUbuntu_20.04/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/graphics_darktable.gpg > /dev/null

bash: Syntaxfehler beim unerwarteten Wort »(«
means: syntax error at unexpected word >>(<<

What is the difference between these commands above and the commands here at the darktable install page?

You will find the working version (Compile with LUA) at this page
https://software.opensuse.org/download.html?project=graphics:darktable&package=darktable

  1. Remove current version
    sudo apt remove darktable

  2. Add the OBS repository

sudo echo ‘deb http://download.opensuse.org/repositories/graphics:/darktable/xUbuntu_20.04/ /’ | sudo tee /etc/apt/sources.list.d/graphics:darktable.list

sudo curl -fsSL https://download.opensuse.org/repositories/graphics:darktable/xUbuntu_20.04/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d /graphics_darktable.gpg > /dev/null

  1. Update Package cache and install new darktable
sudo apt update
sudo apt install darktable

Sorry, it doesn’t work for me.
After installation regarding your proposal (I removed the " ’ " around the deb command in the /etc/apt/sources.list.d/graphics:darktable.list) and

darktable --version

I got still



Lua support disabled



Hallo Andreas,

The error message doesn’t match to the command you’ve posted. The error message complains about an unexpected left bracket (Klammer auf) but there is none in the command you posted.

The first command

echo 'deb http://download.opensuse.org/repositories/graphics:/darktable/xUbuntu_20.04/ /' | sudo tee /etc/apt/sources.list.d/graphics:darktable.list

will add a new installation source by creating the file /etc/apt/sources.list.d/graphics:darktable.list

It’s a “pipeline” with two parts, the first part just prints the text that we need (echo is basically a print command for the shell) and after the “pipe” character | is the command that redirects this text into a file. Only that part needs the sudo.

Next we need to install a cryptographic key, so that the package manager can make sure the .deb packages are genuine and haven’t been tampered with.

curl -fsSL https://download.opensuse.org/repositories/graphics:darktable/xUbuntu_20.04/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/graphics_darktable.gpg > /dev/null

This is a “pipeline” consisting of three parts:

  • The curl command downloads the key file,
  • gpg --dearmor will convert the key
  • sudo tee /etc/apt/trusted.gpg.d/graphics_darktable.gpg will save it to the specified file

To make sure that this was successful, you can run these commands:

user@Ubuntu:~ $ cat /etc/apt/sources.list.d/graphics:darktable.list
deb http://download.opensuse.org/repositories/graphics:/darktable/xUbuntu_20.04/ /

user@Ubuntu:~ $ gpg  --show-keys /etc/apt/trusted.gpg.d/graphics_darktable.gpg
pub   rsa2048 2017-12-26 [SC] [expires: 2022-05-16]
      3247B7519EDBEAB422E900A3040524A84C70D8B5
uid                      graphics:darktable OBS Project <graphics:darktable@build.opensuse.org>

If your output looks the same, you don’t need to repeat these steps.

Maybe you have a different darktable version in your $PATH somewhere.
What’s the (full) output of these two commands?

$ which darktable
/usr/bin/darktable

Click on this link “https://software.opensuse.org/download.html?project=graphics:darktable&package=darktable”

Click on the Ubuntu icon
Click “Add repository and install manually” and you will see the command to execute.
This is what I did and it worked

Hello Oliver @revilo ,
thank you for your comprehensive explanation. Helps me to understand much more. I read it carefully and did what you suggested.
But unfortunately it doesn’t work with Lua support.
I tried it several times. Also the recommendations from Jacques @jadupl2 a tried several times over the last days.

I would like to show you what I did with the commands an the regarding output. Maybe I do still something wrong or you can find hints in the output.

Could it be, the problem is regarding the Lua installation on my OS? I tried to install the Lua version 5.4. on my LinuxMint 20.02

as@KaLM:~$ lua -v

You should remove the ubuntuhandbook repository, as that is from where darktable gets installed, and not from download.opensuse.org.

Now it works!
Thank you all for your help.

Just to clarify: When I copy - pasted the commands after “apt remove daktable” in post # 21 I got an error. Taking them from Install package graphics:darktable / darktable worked fine.
