Error in Pkg.update()

What’s wrong with this problem?

julia> using Pkg

julia> Pkg.update()
    Updating registry at `~/.julia/registries/General.toml`
┌ Warning: could not download
│   exception = Connection timed out after 30003 milliseconds while requesting
└ @ Pkg.Registry /Users/julia/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.7/Pkg/src/Registry/Registry.jl:82

The problem is solved. It is the problem of network.

If you’re in mainland China, you can target to the mirror servers

For instance, downloading from BFSU server would be blazingly fast by setting the environment variable:

julia> ENV["JULIA_PKG_SERVER"] = ""

Thanks very much. It works wery well.
