Cocaine CommandNotFoundError

[Zephyranthes28]

On windows, everything works fine. However I recently migrated to a Ubuntu VPS, and now run into the following error when running my code that downloads a video. (That still works on windows)

Have you installed the cocaine terrapin gem? I think this can be closed 🤔

I have a similar issue. I just installed the gem, when I test it I get Terrapin::CommandNotFoundError (Terrapin::CommandNotFoundError) from the YoutubeDL.download command. After looking into, it seems that this might me an issue of missing dependencies, but I don't know which ones. I've tried installing and removing Terrapin gem, but it's all the same.
