Unable to download packages from https://pub.dartlang.org #1989

samueladekunle · 2018-10-02T17:07:20Z

I am trying to build an application using the Flutter SDK, but on running flutter packages get in the application's directory, what I get is

Running "flutter packages get" in startup_namer...
Got socket error trying to find package cupertino_icons at https://pub.dartlang.org.
pub get failed (69) -- attempting retry 1 in 1 second...

This was initially reported on Flutter's issues page here, but I was directed to post the issue here.

I am not behind any proxy connection, and am located in Nigeria. A fellow Nigerian also complained about this on stackoverflow.

flutter doctor -v prints

Solution

Edited by member of this repository: This is not a solution, hence, I have deleted it as it was confusing people -- see previous version of this common on github, if you really want to know what it said. Notice that https://dartlang-pub-dev.appspot.com/ is a staging site with outdated data, do not use it!

Hello Samuel, has your issue been resolved? Mine isn't working either.

a-oboh · 2018-12-23T12:06:55Z

@samueladekunle I'm also in Nigeria and i faced this same issue. I then resolved to using a VPN, and it worked for me. I think we in Nigeria and some other parts of the world have this issue with some packages.

natebosch · 2018-12-28T00:53:45Z

Is the https://pub.dartlang.org/ site reachable in a browser?

cc @mit-mit

samueladekunle · 2018-12-28T09:14:53Z

@HemlockBane I had to alternate in between a public Wi-Fi and a VPN service for some weeks. But rather strangely, after switching from Windows to Linux, I have not experienced the same issue on my home network.

far11ven · 2019-03-23T11:21:48Z

I'm facing the same issue, @natebosch https://pub.dartlang.org/ is reachable in my browser.
Could it be coz of Corporate laptop I'm using having restrictions? I'm in india btw

leodavinci1 · 2019-03-24T16:11:22Z

Here in Brazil the website https://pub.dartlang.org/ that flutter uses to get the packages with flutter packages get isn't reachable. I tried using TunnelBear VPN connecting to a USA network and it all worked fine.

jonasfj · 2019-03-25T14:44:42Z

@leodavinci1, could you check if this is ipv6 related (or DNS related, try using 8.8.8.8)

leodavinci1 · 2019-03-25T15:58:13Z

@jonasfj Tested with 8.8.8.8 DNS config and the website https://pub.dartlang.org/ worked perfectly. When I removed that DNS config, website became unreachable again.

chenxiaoyanemile · 2019-07-01T02:43:07Z

Hi , i also got this problem in China , do you have a solve way for me ? thanks .

Got the same issue recently while trying to setup flutter. Turn's out I did not set-up the proxy correctly.
If you are also behind a proxy then please make sure you strictly follow the format from https://dart.dev/tools/pub/troubleshoot#pub-get-fails-from-behind-a-corporate-firewall

If you are on Windows and you run the flutter/pub command from PowerShell, the usual recommendation set https_proxy=proxy.yourproxy.com:8080 will not work. The correct ways is:
$Env:https_proxy="proxy.yourproxy.com:8080"

jonasfj · 2019-09-03T14:19:29Z

@fioan89,
Uh, nice trick with PowerShell, please consider contributing to the documentation page you referenced :)

fioan89 · 2019-09-03T14:22:58Z

@jonasfj got it. Thanks for the tip.

lvcster · 2019-09-04T12:37:05Z

Running '$env:https_proxy='proxy.yourproxy.com:8080' on Powershell gives and error =>The filename, directory name, or volume label syntax is incorrect.
Any help?

lvcster · 2019-09-04T12:38:33Z

$

I also tried running without the $, like 'env:https_proxy=proxy.yourproxy.com:8080'. I am not sure if I am missing something.

lvcster · 2019-09-04T12:49:06Z

I found the problem and fixed it...
set https_proxy=proxy.yourproxy.com:8080 must be wrapped within single quotes like
set https_proxy='proxy.yourproxy.com:8080'. This is in Windows.

fioan89 · 2019-09-04T13:10:50Z

:( weird, according to this Microsoft page it should work.

What version of PowerShell do you have?
Are you using some kind of special characters in the proxy name? Anything outside a-z A-Z or 0-9?

fioan89 · 2019-09-04T13:36:27Z

Running '$env:https_proxy='proxy.yourproxy.com:8080' on Powershell gives and error =>The filename, directory name, or volume label syntax is incorrect.
Any help?

Are you sure you are running this with PowerShell and not Command Prompt? :) I just ran the expression in Windows Command Prompt and it returns the exact same error as you mentioned.

tejiriadjogbe · 2019-09-24T16:56:13Z

Had thesame issue from Nigeria. I think the issue maybe from my network provider. I fixed it following by declaring PUB_HOSTED_URL as a system environment variable and give it the value https://pub.dev/

You may need to restart your command prompt window for the changes to take effect.
don't know if it helps

vishnuagbly · 2020-05-02T13:46:08Z

please do not just copy blindly above solution given by @samueladekunle , you may need to create PUB_HOSTED_URI, but probably link that you need to enter is dependent on your location, for ex- for me it was https://pub.dev/ instead

Tarhex · 2020-05-16T18:27:12Z

Try to see if you can reach https://pub.dev/ in your browser

If it is accessible, declare PUB_HOSTED_URL as a system environment variable and give it the value https://pub.dev./

Then exit and reopen your cmd window and try again.

Edit:

Changed ' https://dartlang-pub-dev.appspot.com/' to ' https://pub.dev/' based on @jonasfj correction

jonasfj · 2020-05-16T19:11:42Z

Do not use https://dartlang-pub-dev.appspot.com/.

This is a staging site used for development and stuff.. data is outdated and often incorrect.

Hey everyone !

patrickubong · 2023-02-06T10:00:15Z

This a straight forward solution, just get a VPN and use US IP address and you will be fine. Using Free version of ProtonVPN with free US IP worked for me. Flutter Doctor and Pub Get issues resolved instantly
