Do you know if there’s a Github outage going on now? I keep getting an issue with libvorbis on Windows 10 and Julia version 1.7.1 trying to update my packages.  I used DebugArtifacts.jl and all the output looks (to me) like it’s okay.
Error message from trying to update:

Based on another post I also tried to rename my .julia folder and then relaunched Julia to recreate the .julia folder.  I then tried to do a fresh install of some packages and both of Distributions.jl and GLM.jl gave me a similar error but for the Rmath artifact.  Perhaps that means this is a wider/Github issue right now?
