OP, I would seriously consider trying the Arch Wiki for this. I really hope you had a backup, but you probably need expert-level advice here (at least below “paid data recovery specialist”) if you have any hope of unfucking this. Obviously you’ve learned your lesson about running random commands you don’t understand in response to an error message, so I don’t think people should be scolding you for that.
