Checksum error building or installing

[j0ni]

I've encountered this same error now using Nim 2.0, and 2.1.1 (devel version) installed both via choosenim and directly by my package manager (Arch pacman/paru), including choosenim installed directly using the shell installer, and installed using pacman.

Installing the langserver using nimble, or cloning this repo using git and attempting a nimble build always ends like this:

Downloading https://github.com/nim-lang/Nim.git using git

    Error:  Downloaded package checksum does not correspond to that in the lock file:
        ...   Package:           nim@v.2.1.1@r.940b1607b8459b4b7b7e20d316bec95c8de85809
        ...   Checksum:          265df7fa3db8a93d9ba6a89b7376a6d5346f2391
        ...   Expected checksum: ee369ca2ef4fd48e55732c09c5f8b67a4a22daa4

I was able to make it build by deleting the lock file and invoking nimble lock, but I did have to delete the lock file - contrary to the nimble usage output, it did not update the existing lock file.

I also wasn't able to even get nimble to output usage info within the project root - even with nimble --help it attempted to build the project and failed. I don't think that's a problem with this project though.
