CRC doesn't match, file is corrupted

I was just following the instructions here

I got to the point where I see “Kaleidoscope keyboards” in the Boards Manager section of Arduino IDE. I tried to install 1.99.3 and this error message comes up.

I am using Arduino 1.8.16.

I looked at the link

seems like it is pulling a LFS cache. Is that the reason why? that we are just downloading the lfs entry and not the actual file? What do I do?

Any help would be welcome.

Hmm, might be a GitHub bug. What happens if you do a git clone and then check out the tag yourself? That should be equivalent.
