Tree hash mismatch error when installing on WSL

I am getting a `Tree Hash Mismatch!` error when trying to install SpecialFunctions.

Setup:
- julia 1.3 : fresh install, I just have Revise installed
- windows subsystem for linux (WSL)

Full error message with step to reproduce:
```
(v1.3) pkg> add SpecialFunctions
