dtMediaWiki will not be loaded

[surveyor54]

Hello, me again

I installed a new version 3.8.0 of darktable , now dtMediaWiki doesn't work anymore.
I get the following error message: "contib/dtMediaWiki failed to load".

What could be the reason for this?

I don't know, unfortunately I can't reproduce here, it starts without issues on Arch Linux with darktable 3.8.0.

What OS are you using? Do you have any other plugin that works (or doesn't)? Does anything else relevant show up when you run "darktable -d lua"? (make sure you don't copy your password from the initial HTTP request)

Hi,
I am using ubuntu 20.04.3
I have run darktable -d lua and get the following error message:

1,442194 LUA ERROR : ...e/darktable/lua/contrib/dtMediaWiki/lib/mediawikiapi.lua:18: module 'ssl.https' not found:

I see this is looking for lua 5.4, I have version 5.3.3 installed.
What can I do?
I installed lua 5.4.3, but had the same error.

Ah, what I had forgotten, the folder "/usr/local/share/lua/5.4" is empty.

Does it work now? It seems the lua-sec library was missing, you would have to install it for the version of Lua darktable is using (which can be different from that installed on your system, I believe).

It looks like the Ubuntu 20.04 package for lua-sec only goes up to Lua 5.3 (per https://packages.ubuntu.com/focal/amd64/lua-sec/filelist ), so you will have to find another way to install lua-sec for Lua 5.4.

You can probably directly get it from its repository https://github.com/brunoos/luasec or maybe the LuaRocks package manager would help.

I've tried everything, I can't get it to work. I cannot install lua-sec for Lua 5.4.
The LuaRocks package manager could not help either.
I try it in a few months once more, may be lua-sec works with Lua 5.4.

Any luck? It looks like Ubuntu 24.04 ships lua-sec for Lua 5.1 through 5.4
