WSL2(Ubuntu)+cntlm 環境でAWS CLIが繋がらない

環境  
Windows 10  
Ubuntu 22.04  
cntlm 0.92.3  
aws-cli 2.8.12

Windows 10 でのWSL2(Ubuntu 22.04)からAWS CLIを利用したいのですがプロキシで拒否されてしまいます。  
ntlm認証のプロキシを経由するためcntlmをWSLで実行しています。  
WSL上からcurlコマンドを実行してhttps://ec2.ap-northeast-1.amazonaws.com/ に繋がることは確認済みです。  
また、ホストOSのWindows 10で同様にcntlmを利用してAWS CLIを利用できることも確認済みです。  
WSL2(Ubuntu 22.04) のAWS CLIのみ接続できません。

```

何か設定が足りないのか、ご教示いただきたいです。

question
wsl aws-cli
WSL2(Ubuntu)+cntlm 環境でAWS CLIが繋がらない
AWS CLIではNTLMプロキシがサポートされていないようです。  
[AWS Command Line Interface - HTTP プロキシを使用する -
プロキシを認証する](https://docs.aws.amazon.com/ja_jp/cli/latest/userguide/cli-
configure-proxy.html)

```

    $ export HTTP_PROXY=http://10.15.20.25:1234
    $ export HTTP_PROXY=http://proxy.example.com:1234
    $ export HTTPS_PROXY=http://10.15.20.25:5678
    $ export HTTPS_PROXY=http://proxy.example.com:5678
    
```

の例の下に以下の記事があります。

> AWS CLI では NTLM プロキシはサポートされていません。NTLM または Kerberos  
>  プロトコルプロキシを使用する場合は、Cntlm などの認証プロキシを介して接続できることがあります。

UbuntuでCntlmを使えば接続できるかもしれませんが、  
**プロキシ経由ということは企業、学校などの環境からつなげるのだと推測します。  
プロキシをかいくぐることになるため、組織のセキュリティ部門とCntlmの利用について相談することをお勧めします。**

とのことで、具体的な手順が開示されていないのでわかりませんが、同じ設定をすればいいのではないでしょうか。

> OSError: Tunnel connection failed: 407 Proxy Authentication Required

と言っていますのでProxy認証情報が必要です。curlにはどのように渡したのでしょうか？

[AWS Command Line Interface - HTTP プロキシを使用する -
プロキシを認証する](https://docs.aws.amazon.com/ja_jp/cli/latest/userguide/cli-
configure-proxy.html#cli-configure-proxy-auth)には

```

    $ export HTTP_PROXY=http://username:password@proxy.example.com:1234
    $ export HTTPS_PROXY=http://username:password@proxy.example.com:5678
    
```

という例が載っています。
