It seems you'v configured source replacement (a.k.a. mirrors). Check your .cargo/config.toml. Comment out [source] table and see if the original crates.io registry has the same issue.

from cargo.

@weihanglo I just installed Rust and created new project using "cargo new project-name" cli and executed "cargo build".
When i check ~/.cargo folder, I'm not able to see any config.toml file present.

If you look in your cargo.lock for the section about autocfg v0.1.8, what is there?

from cargo.

Cargo's error for this case will indicate source replacement even when it's not explicitly configured due to the built-in sparse replacement of crates.io, so it's possible that no source replacement is configured here. I just opened #13433 to improve the errors.

Can you check if ~/.cargo/registry/cache/index.crates.io-6f17d22bba15001f/autocfg-0.1.8.crate exists? That's where it will be downloaded by default if a source replacement is not configured.

Another way to check (if you have nightly available) is to run cargo +nightly -Zunstable-options config get source. If it gives you an error, then no source replacement is configured.

from cargo.

~/.cargo/registry/cache/index.crates.io-6f17d22bba15001f/autocfg-0.1.8.crate it is not created for me.

from cargo.

There is no cache folder present under ~/.cargo/registry

Rather I have below file present for autocf.
