choco proxy support

[JonCubed]

I'm using chocolatey in automated builds to install some stuff and the http_proxy and https_proxy environment variables do not work in 0.9.9.

The documentation https://github.com/chocolatey/choco/wiki/Proxy-Settings-for-Chocolatey appears to be wrong.

I have solved this by adding

  <system.net>
    <defaultProxy>
      <proxy proxyaddress="<proxyserver>" />
    </defaultProxy>
  </system.net>

to chocolatey.config and also updating Get-WebFile.ps1 & Get-WebHeaders.ps1 in /helpers/functions to setup the proxy even if $webclient.Proxy.IsBypassed($url) returns true

Would be nice if the environment variables where supported again.

Yes. Have the same issue. Would be great is environment variables are supported.

Many thanks.

Thanks for creating this with things that can be done to fix this as well!

Found more information on this. Has to do with the config needing not to be blank. We'll likely need to override the defaults, which don't find the chocolatey.config and don't find the nuget.config unless it exists (but that is not an optimal way to go about it).

For now a workaround is to create the Nuget.Config file like before with the right settings, see https://docs.nuget.org/consume/nuget-config-file for location and reference.

This is issue chocolatey-archive/chocolatey#404 from the old repo.

There also seems to be a problem even if the proxy is configured in IE. I have the proxy set up in IE and have it set in the environment variables http_proxy and https_proxy. I installed choco by manually downloading and then running the installer in powershell. But when I try to intstall ag for example, I get this error (proxy address edited), v0.9.9.6:

 Using this proxyserver: my.proxy.server
 Using this proxyserver: my.proxy.server

The install of ag was NOT successful.

 See log for details.

The proxy requires username and password authentication.

Before I had set up the http_proxy and https_proxy variables choco asked me for proxy credentials, but not the address. It also seems to have verified those credentials, as when I tried it with false credentials I got an error. Still, even then it trew the 407 error.

Thanks for the information. I may have something for testing over the next couple of weeks if you are interested. This one is a bit harder for me as I don't have a proxy myself. I know that nuget.core will accept those proxy credentials in the config, which I think we need to ensure the download will also look at those values.

Sure, I can help you test.
Thanks for looking into this.

[JonCubed]

Happy to test as well when a fix is available

Hi,

I can help test this when the fix is ready. The nuget config workaround doesn't seem to work so unfortunately we can't use chocolatey at the moment :-(

Thanks

@ifunky You can use 0.9.8.x series. You may also want to try to set a file next to choco.exe named choco.exe.config with the xml configuration settings in it (untested).

Create a file at C:\ProgramData\Chocolatey\choco.exe.config (based on the default install location, make sure it sits next to $env:ChocolateyInstall\choco.exe) with the following contents:

<?xml version="1.0"?>
<configuration>
  <appSettings />
  <system.net>
    <defaultProxy>
      <proxy proxyaddress="<proxyserver>" />
    </defaultProxy>
  </system.net>
</configuration>

[ifunky]

Thanks for the quick response - the choco.exe.config didn't work but putting the proxy settings as above in machine.config did the trick!

Cheers
Dan

[GuillaumeBonamy]

@ifunky What do you mean by machine.config?

[ferventcoder]

@GuillaumeBonamy the one for .net framework. Only do that if you want it to affect ALL .net applications.

[ferventcoder]

This is pretty much complete. Take a look at https://github.com/chocolatey/choco/wiki/Proxy-Settings-for-Chocolatey#explicit-proxy-settings for information on how to set this up once 0.9.9.9 rolls out the door.

[ferventcoder]

Merged into stable at bfa8ccf - will be released in 0.9.9.9.

thanks a lot @ferventcoder
