Travis CI + NuGet产生无效证书错误

Question

我正试着在特拉维斯上用NuGet

- sudo apt-get -qq -y update
- sudo apt-get -qq -y install mono-complete gtk-sharp2
- wget https://dist.nuget.org/win-x86-commandline/latest/nuget.exe
- mono ./nuget.exe install ILMerge -Version 2.14.1208

不幸的是，我得到了以下错误：

  https://api.nuget.org/v3/index.json

Attempting to gather dependency information for package 'ILMerge.2.14.1208' with respect to project '/home/travis/build/craftr-build/craftr/build/.nuget-artifacts', targeting 'Any,Version=v0.0'
Invalid certificate received from server. Error code: 0xffffffff800b0109

我已经尝试了我在谷歌上找到的各种推荐，例如，在尝试使用NuGet之前使用以下内容：

- mozroots --import --sync
- yes | certmgr -ssl -m https://go.microsoft.com
- yes | certmgr -ssl -m https://nugetgallery.blob.core.windows.net
- yes | certmgr -ssl -m https://nuget.org

不幸的是，mozroot命令给出了

Downloading from 'http://mxr.mozilla.org/seamonkey/source/security/nss/lib/ckfw/builtins/certdata.txt?raw=1'...
Couldn't retrieve the file using the supplied information.

省略mozroot命令会产生相同的NuGet错误。

我怎样才能让NuGet在特拉维斯上工作？

我现在只用了APT插件。我在另一个单声道项目here中找到了sourcelinse和key_urls

addons:
  apt:
