Pkg.add stays stuck at 99.9% for 20+ minutes at a time. I’ve tried installing the following packages:  
QuadGK  
LinearAlgebra (already natively installed, but still hangs)  
Optim

I’ve attempted other solutions like removing the registries\General folder, reinstalling, calling Pkg.registry.add(“General”), etc. and they haven’t worked so far.

On which operating system?  
And did you check your internet connection?  
Sufficient disk space?

This is using Windows and the Ubuntu windows subsystem  
There is sufficient disk space and a working internet connection

Sorry for not having very much information, I’m not getting any specific errors- only hanging.  
When I cancel (ctrl + c) it usually takes a few minutes, and eventually only returns an interrupt error.
