I'm having trouble installing Chocolatey packages from behind a corporate proxy. Internet Explorer is correctly configured but I'm having issues getting it to work through Powershell.
I can use the Web-Client to download pages eg Microsoft.com, but ultimately Chocolatey fails to download packages with the prompt "Please provide proxy credentials:" which will not accept my domain login as being valid. Sometimes I just get the error "Exception calling "DownloadFile" with "2" argument(s): "The remote server returned an error: (407) Proxy Authentication Required."
I have two machines - one of them can download the packages fine, and the other gives the errors above, but they both show Direct access (as below):
PS C:\Windows\system32> netsh winhttp import proxy source=ie
Current WinHTTP proxy settings:
Direct access (no proxy server).
PS C:\Windows\system32> netsh winhttp show proxy
Current WinHTTP proxy settings:
Direct access (no proxy server).
I'm not too sure what is happening here. Any suggestions?
Chocolatey has proxy instructions at https://github.com/chocolatey/choco/wiki/Proxy-Settings-for-Chocolatey and specifically the section on explicit proxy . Ensure you have the proper version of choco installed for that to work. If that is incorrect, we should fix the documentation/choco to make it correct.
For posterity:
Explicit Proxy Settings
Chocolatey has explicit proxy support starting with 0.9.9.9.
You can simply configure 1 or 3 settings and Chocolatey will use a proxy server. proxy is required and is the location and port of the proxy server. proxyUser and proxyPassword are optional. The values for user/password are only used for credentials when both are present.
choco config set proxy <locationandport>
choco config set proxyUser <username>
choco config set proxyPassword <passwordThatGetsEncryptedInFile>
Example
Running the following commands in 0.9.9.9:
choco config set proxy http://localhost:8888
choco config set proxyUser bob
choco config set proxyPassword 123Sup#rSecur3
I had a similar issue except that Chocolately wouldn't install in the first place due to the corporate proxy.
Was able to resolve this based on this blog post as follows:
cmd
-> right-click on "Command Prompt" and select "Run as Administrator") . @powershell -NoProfile -ExecutionPolicy Unrestricted -Command "[Net.WebRequest]::DefaultWebProxy.Credentials = [Net.CredentialCache]::DefaultCredentials; iex ((New-Object Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%systemdrive%\\chocolatey\\bin
choco
command - if all is OK it should now output the Chocolatey version and help text. Further note for node.js: I did the above after installing Node.js with the option ticked to install the extra tools/requirements including Chocolatey. Was then able to continue the failed installation via Apps & features -> Node.js -> Modify. I then followed the instructions here to configure npm for the corporate proxy.
