Update fails when a package is installed from a custom registry #128
Description
I have a binary which is installed from a custom registry. Now cargo install-update -l or cargo install-update -a fails with
Updating registry 'https://github.com/rust-lang/crates.io-index'
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: "package ... not found"', src/libcore/result.rs:1188:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Is there a way to search all configured registries or maybe even just skip the failed packages?
