Please don't trust random distro packages of Ladybird, we have no idea what they're packaging, but it's unlikely to be current, and not something we can help you with.
I wish distros would not package pre-alpha software, since the only thing it accomplishes is giving people a bad first impression of something that isn't ready :(

If you want to mess with Ladybird, build it from the source at https://github.com/LadybirdBrowser/ladybird :)
