cargo update failed on raspberry pi, error inflating zlib stream

[yeshengm]

Problem
I have Arch Linux installed on a Raspberry Pi 3b (armv7-unknown-linux-gnueabihf). When I run cargo build, I have the following error:

Caused by:
  failed to load source for dependency `cc`

Caused by:
  Unable to update registry `https://github.com/rust-lang/crates.io-index`

Caused by:
  failed to fetch `https://github.com/rust-lang/crates.io-index`

Caused by:
  error inflating zlib stream; class=Zlib (5)

Fixes like removing ~/.cargo/registry do not seem to work.

Steps

cargo update

Possible Solution(s)

Notes

Output of cargo version:
cargo 1.45.0-beta (744bd1fbb 2020-06-15)

Does this persistently happen? If you switch to a different CARGO_HOME temporarily does it still happen? (curious if this is either an intermittent issue or due to a corrupt repository)

I have the same effects.

For me the problem is not just happening on the rpi, but also during a docker buildx to cross complile for arm/v7.

My exact failed message is:

This is happening in a clean container FROM rust:slim-buster

@technimad that looks like a separate issue (different error message). If you can provide reproduction steps so we can help debug that it would be very useful!

I'm pretty sure my issue is a duplicate of #7451

@alexcrichton This seems to be a transient issue. But I have no idea why it doesn't work before. But anyway it works now! Thanks!
