Hi @smallnest, I'm sorry nobody responded to your issue. Are you still able to reproduce this issue with the latest nightly version of cargo? I've been unable to find a way to get it to happen, and I'm a bit confused why it is trying to start an SSH session for an https url.

If you can still reproduce it, can you copy your git configuration (git config --list, remove any sensitive values if any)?

[smallnest]

I think it should be caused by my proxy.
It is not cargo problem.

I have updated my proxy, cargo works well.

Thanks @ehuss

I've exactly the same issue. I reckon it was related the powershell hijack ssh keyword.

[Update]
I was wrong. It was not powershell try to alias ssh. I've OpenSSH installed. However, this doesn't contribute to the issue I think.

I have created a config file at CARGO_HOME with the content below fix this issue

[net]  
git-fetch-with-cli = true

Thanks @singlewind :)

Hi,
I have the same issue. It's been a while since I worked with Rust and it used to run just fine. When I return a few days ago, and try to cargo build, I got the same error:

    Updating crates.io index
error: failed to get `rusqlite` as a dependency of package `xxx v0.1.0 (C:\Users\xxx\Documents\Projects\Rust\xxx)`

Caused by:

I am running on Windows 10.

Here is my git config:

When I tried @singlewind 's solution, I got this error:

Please make sure you have the correct access rights
and the repository exists.

On the other hand, I can still use git to fetch and push my repositories at github with no problem.

Any idea what's going on? Any possible solutions?

Thanks.

I found the solution. In my case, I have to change my .gitconfig file and comment out the following:

[url "[email protected]:"]
    insteadOf = https://github.com/
