You couldn't download libc v0.2.70. Maybe check your firewall and internet connection.

That is very strange! I see someone else encountered something similar at rust-lang/rust#55924. Somehow the file has been corrupted. You can delete that directory (libc-0.2.70), and try again and see if it clears up? I don't have any ideas what could cause that though.
