Have this problem solved? I meet the same issue........

[jneumann]

Any word on this? I'm running into the same issue and I can't figure out what's wrong.

[lambda]

@GildedHonour When you copied and pasted that URL into curl, you copied some extra text as well, which caused your error.

When I run curl https://static.rust-lang.org/dist/channel-rust-stable.toml.sha256 I get what looks like a valid sha256 file:

$ curl https://static.rust-lang.org/dist/channel-rust-stable.toml.sha256
10da11872e920f56826d8a6ba63712a24f4d44d3f31d800c311d9ae9207cf28e  channel-rust-stable.toml

In #1400, @jneumann writes "When I ran the command with --verbose, the file it was trying to download was the *.toml.sha256 file, which I can manually download via curl without issue."

For me, both rustup and curl work, so we might need some more information from those for whom it doesn't work to debug the issue.

To debug such a problem, it would be useful for someone seeing the problem to try doing a packet capture during the rustup command and the curl command to see how the HTTP request and reply differ. If you are on a linux system and have tcpdump installed, you should be able to run tcpdump -s0 -w rustup-issue-1328.pcap -i <your-ethernet-or-wifi-device> tcp port 443 or udp port 53, and while that is running try the download with both curl and rustup. It will be helpful if you don't have anything else running which might be doing HTTPS or DNS requsts, so you only capture traffic generated by these two commands.

That resulting rustup-issue-1328.pcap file can be viewed in Wireshark or posted on CloudShark to see what is going on differently between rustup and curl when accessing this file.

[lambda]

A few other things that I might use to debug the issue: run strace on rustup and curl to see what files they are each opening; it could be possible that they are using different certificate stores, or different proxy settings, or the like.

[jneumann]

@lambda Thanks for the tips. I narrowed it down to an issue with my ISP's DNS. Unfortunately, I don't know enough about how the Internet works to narrow it down further.

[Diggsey]

@GildedHonour @sgy1993 can you confirm whether changing your DNS fixes the problem? (eg. try google's DNS on 8.8.8.8)

[godwinchang]

When install 1.28 on macos, this problem occurs.

Welcome to Rust!

This will download and install the official compiler for the Rust programming
language, and its package manager, Cargo.

It will add the cargo, rustc, rustup and other commands to Cargo's bin
directory, located at:

  C:\Users\xxxx\.cargo\bin

This path will then be added to your PATH environment variable by modifying the
HKEY_CURRENT_USER/Environment/PATH registry key.

You can uninstall at any time with rustup self uninstall and these changes will
be reverted.

Current installation options:

   default host triple: x86_64-pc-windows-msvc
     default toolchain: stable
  modify PATH variable: yes

1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

Having this exact problem on a fresh Ubuntu 18.04 install no it's not my router or DNS, other machines on the same network and DNS work fine

[dalance]

I have the same issue on https://build.snapcraft.io.

This issue occurred on armhf only.

[kinnison]

@dalance Is there a non-standard network setup in the snapcraft build environment? Rustup defaults to making direct connections unless there's an appropriate proxy configured in the environment. If snapcraft relies on an altered curl library or somesuch then rustup won't be able to work there.

[dalance]

@kinnison Thank you for your suggestion. Snapcraft environment seems to use proxy.
I ran some test script on the environment. rustup with curl-backend is OK, and rustup with reqwest-backend is NG.

[kinnison]

Okay, that's interesting. Does cURL still manage to download if you unset the proxy environment variables? rustup should honour those environment variables using the reqwest backend, so perhaps something else is in play?

[dalance]

If unset, cURL can't download.

$ unset http_proxy
$ unset https_proxy
$ curl https://static.rust-lang.org/dist/channel-rust-stable.toml.sha256
curl: (6) Could not resolve host: static.rust-lang.org

[kinnison]

@dalance Fascinating, our reqwest backend really ought to be working with all that. I wonder what's going on. I will be at Snapcraft Summit next week in Montréal, so if you could possibly provide details of how to reproduce that environment I will see if I can debug it while with Snappy people.

[RainKolwa]

It worked after I disabled network proxy...

[kinnison]

@RainKolwa It would be super-helpful if you could provide an example of your proxy setup. Our shift from cURL to reqwest as an HTTP backend should have been feature-compatible, but clearly it's not quite.

I mean I disabled the Proxy, actually I was using shadowsocks, and then I turned it off.

[kinnison]

Aah so you had a proxy but hadn't got the environment variables for it. I understand, okay thanks.

[rbtcollins]

@kinnison shadowsocks is a MITM socket level proxy - https://shadowsocks.org/en/index.html - not an HTTP proxy.

I think this is a case of an attractive-nuisance bug title: its likely that none of the reports are connected, but they all show the same error, so we have a dogpile. I suggest closing this and being super quick about retitling all new reports.

[kinnison]

I agree with that, and will close this now. For future download problems, please file new issues with specific titles.

I have strat Tor ( service tor start ) of course after installing the Tor.
Then install Rust.

I'm experiencing this error today. I am not on a VPN nor have a proxy. Curl doesn't seem to have an issue though.

@felipenoris In future it's better to open a fresh issue for new problems. In this case though, we're aware there's a bug in the proxy code and we're working on getting a fix out ASAP.

[dzhang-b]

confirmed. same error when the machine is behind a proxy with http_proxy environment var set.

[kinnison]

@dzhang-b Please either find an open issue which appears related, or else open a fresh issue with your situation in it. Especially important is to consider the error you get if you specify --verbose when updating; and also the kind of proxy you're trying to use.

[dzhang-b]

@kinnison Sure. I will open a new issue with it.

[thardie]

What a spectacularly bad experience for new rust users. I have this same error. I have no http or https proxies set. Curl can download just fine WITHOUT a proxy. Very bad first impression of this. Standard Ubuntu 20.04 LTS

@thardie That is very unfortunate looking. Could you please open a fresh issue so that we can discuss things there? Though when you do, please include some indication of your IP setup (both v4 and v6) since I'm starting to suspect this is something to do with falling back from v6 to v4 incorrectly.

Seems to be something with the openssl connection, so let's check that. At first it gives return code 20 (error):

openssl s_client -connect static.rust-lang.org:443 -servername static.rust-lang.org -showcerts < /dev/null

...

Testing the openssl connection with my certs directory specified then gives return code 0 (OK):

openssl s_client -connect static.rust-lang.org:443 -servername static.rust-lang.org -showcerts -CApath /etc/ssl/certs/ < /dev/null

It definitely seems related to SSL/OpenSSL somehow but it's beyond my knowledge how to take it from here. Suggestions?

Probably a problem with network settings, for normal work just try Cloudflare WARP. Working for me.

[CastelloDev]

I had the same issue, what worked for me was removing my .ssh/config file. Then running the command again.

[fly-duck]

1. unset http_proxy
2. unset https_proxy
3. Then turned off network proxy through network setting.
   Those 3 steps work for me.

See #1400 (comment), this was my case inside a Docker container. Don't know what network config inside the container made the reqwest backend unusable.

[zzrs123]

if you are in china, try use aliyun source.
"try again" is truly a good suggestion.

[adamjc]

Same issues here, using wsl

[rem-aster]

@adamjc
try disabling vpn/proxy, terminate wsl (ex: wsl -t Ubuntu) and then try installing again, it worked for me.

[rzr]

Thanks for hints I sorted it by disabling vpn that break SSL root of trust...

It would help to have rustup-init supporting an envar like RUSTUP_USE_CURL=1 to allow insecure download
