Unexpected internal cargo error when publishing to crates.io

[konstin]

We had our latest release to crates.io fail with the following message:

error: no packages ready to publish but 2 packages remain in plan with 1 awaiting confirmation: uv v0.11.20 and uv-cli v0.0.53
note: this is an unexpected cargo internal error
note: we would appreciate a bug report: https://github.com/rust-lang/cargo/issues/
note: cargo 1.97.0-nightly (eb94155a9 2026-04-09)

I think this is fixed by #17071 (see also #17028), but I haven't yet updated the toolchain to rust-lang/rust. Let me do it right now.

[weihanglo]

rust-lang/rust#157760

So should be available in next or next next nightly.

Amazing, thank you!

rustup toolchain install nightly-2026-06-12 should have the fix. Resovling.
