warning: spurious network error

Problem

So running the below command to build a static version of Rav1e I get a spam error code.
cargo cinstall --prefix=/home/jman/tmp/ffmpeg-build-script/workspace --library-type=staticlib --crt-static --release

The error is

warning: spurious network error (1 tries remaining): [6] Couldn't resolve host name (Could not resolve host: index.crates.io)
warning: spurious network error (1 tries remaining): [6] Couldn't resolve host name (Could not resolve host: index.crates.io)
warning: spurious network error (1 tries remaining): [6] Couldn't resolve host name (Could not resolve host: index.crates.io)

warning: spurious network error (1 tries remaining): [6] Couldn't resolve host name (Could not resolve host: index.crates.io)

Steps

1. curl -sSf --proto '=https' --tlsv1.2 'https://sh.rustup.rs' | sh -s -- -y &>/dev/null
2. cargo install --version '0.9.29+cargo-0.76.0' cargo-c
3. curl -Lso rav1e-0.7.1.tar.gz 'https://github.com/xiph/rav1e/archive/refs/tags/v0.7.1.tar.gz'
4. unpack the tar.gz
5. cd into dir
6. cargo cinstall --prefix=/home/jman/tmp/ffmpeg-build-script/workspace --library-type=staticlib --crt-static --release
7. the error message spams over and over

Possible Solution(s)

I had to run
cargo build --release
then I ran
cargo cinstall --prefix=/home/jman/tmp/ffmpeg-build-script/workspace --library-type=staticlib --crt-static --release
and it installed.

Could you check if you can resolve the hostname index.crates.io with other CLI tools? Such as

• curl https://index.crates.io
• dig index.crates.io
• nslookup index.crates.io

You might also want to check any of the config under [http] to make sure the connection is configured currently for your local environment

same or similar problem here cargo 1.46.0

• create an ubuntu16.04 server in the cloud
• apt update && apt install cargo
• cargo install boringtun-cli (or whatever, nothing works)

I have got the same problem. I use devcontainer on Ubuntu 22 box.

For devcontainer, see #6513 (comment) for possible fixes.

For cargo 1.46.0, that is not a supported version of Cargo. Please use the latest version and we can debug it.

I am going to close this as the original author hasn't yet responded for a while. Please check #6513, which has different symptoms and solutions. Thank you.

when I had this problem, I initially thought that something got corrupted in my rust global setup, so I removed rust and tried to install again, because nothing else helped. Then to my astonishment I saw I can't even download rust from the official website. That was something wrong with my network, not sure what suddenly happened, but using mobile hotspot resolved the issue 🤷‍♂
