invalid or unknown remote ssh hostkey

[dsully]

I'm getting a failure when using cargo-update, which has worked fine until recently:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error { code: -17, klass: 23, message: "invalid or unknown remote ssh hostkey" }', /Users/dsully/.cargo/registry/src/index.crates.io-6f17d22bba15001f/cargo-update-13.0.1/src/ops/mod.rs:496:149

This is repeatable. I've tried removing github.com from my .ssh/known_hosts just in case.

That's for a git package, what's your ~/.cargo/.crates.toml?

What if you export CARGO_NET_GIT_FETCH_WITH_CLI=a=true?

[dsully]

That works. config.toml is:

# Use the new sparse registry.
[registries.crates-io]
protocol = "sparse"

[nabijaczleweli]

Does it also happen without -g, and if not, what's your .crates.toml?

[dsully]

"cloudflare-dns 0.0.1 (git+git+ssh://git@github.com/dsully/zoned#8cd2481c664b3dc49929272ff23cb6d61a78995e)" = ["cloudflare-dns-updater"]

Is the line you're looking for from .crates.toml

I'm not calling cargo-install-update directly, but rather from topgrade. It is passing --git:

https://github.com/topgrade-rs/topgrade/blob/ac6330fac85564832170237379a226f1f16545bf/src/steps/generic.rs#L59

funnily enough, I get:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error { code: -1, klass: 23, message: "error loading known_hosts: " }', src\ops\mod.rs:496:149
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

on win32 and

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error { code: -17, klass: 23, message: "invalid or unknown remote ssh hostkey" }', src/ops/mod.rs:496:149
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

under linux. or i did the first few times before i got throttled. idk, looks like libgit2 URL parsing bull shit. set net.git-fetch-with-cli = true for now if running git works

And now my repro says
