Registry Update `https: // example.com /`

Question

Like https://github.com/DaGenix/rust-crypto , I added this to my rust-lib project:

//Cargo.toml [dependencies] rust-crypto = "*" //lib.rs extern crate "rust-crypto" as rust_crypto; 

And got the following:

 $ cargo build --verbose Updating registry `https://example.com/` Unable to update the package registry Caused by: failed to fetch `https://example.com/` Caused by: [16] hostname does not match certificate 

There is no "example.com" neither my project nor its lib.

Answer 1

I'm not sure why you are understated.

You can only have old Cargo when the registry was installed on example.com. When was the last time you installed it?
