TLS error with no firewall

[SlavaSkvortsov]

Environment

• Dart version (run dart --version):

Dart SDK version: 2.19.6 (stable) (Tue Mar 28 13:41:04 2023 +0000) on "linux_x64"

• OS kind and version (e.g. "Windows 10, version 1809" or "macOS 12.4"):
  Ubuntu 22.04.2 LTS
• Are you using the Chinese community mirror or a corporate firewall?
  Nope

Problem

Trying to install flutter for the first time, but flutter doctor fails from the beginning because of Got TLS error trying to find package test at https://pub.dev. I'm not behind a farewell, curl https://pub.dev/api/packages/test returns the data. Was trying to add a cert as recommended here, but it changed nothing.

Expected behavior

All should work 🤷‍♂️

Actual behavior

Returns the error

--trace output

Was trying to add a cert as recommended #1882 (comment), but it changed nothing.

Why would you need to add a certificate?

TLS aims to ensure that you are talking to our server pub.dev.

Some people have software/proxies that intercept their TLS connections. But unless you know that you have this, or have an IT admin telling you to install a custom certificate, I'm not sure why this would be necessary.

I'm not sure why this would be necessary.

Yeah, neither am I, I just wanted to show that I tried many options to solve the issue, even as weird as this one. None of them helped. If I'm running it w/o any cert specified I get the same result

[sigurdm]

Can you try running: https://github.com/dart-lang/pub-dev/blob/master/app/bin/tools/check_domain_access.dart and post the output? That will hopefully give us more information about your network.

Without additional information we're not able to resolve this issue. Feel free to add more info or respond to any questions above and we can reopen the case. Thanks for your contribution!

Hello, I'm having similar issues, and this is the result of running check_domain_access.dart

不知道这样的主机 means unknown host, I'm guessing this is an DNS issue? but I can ping the domain:

@fengjiongmax were you able to find a solution for this? getting the exact same issue.

[fengjiongmax]

@Harshitk-cp I can't recall what I did to resolve this, sorry.
Maybe you could try reinstalling Flutter? or using Flutter behind a proxy: https://stackoverflow.com/questions/65555508/use-http-proxy-in-flutter?

[dizzib]

The following resolved this TLS error for me on Alpine linux…

apk add ca-certificates
