写在开始最近打算将原来用的Drone换成Jenkins来着，然后迁移我的DotNet项目，尝试用非Docker方式构建的时候/root/.dotnet/sdk/5.0.404/NuGet.targets(131,5): error : 'N/A' is not a valid version string. (Parameter 'value') 我就非常纳闷，这个神奇的情况，因为我在 Jenkins Runner 的机器上手动执行的时候并没有遇见错误。解决方法看了一下环境变量，看到里面自己加了一个环境变量，export version='N/A'然后就觉得可能是这个原因了，于是手动测试了一下加了这一行环境变量，果然如此。于是在 Jenkinsfile 里面手动加一个version的环境变量，问题解决。写在最后挺无语的一个问题的，开始找了半天也没找到问题所在。以为是缺了啥环境变量，结果检查了一下发现并没有缺，没想到实际上是多了一个环境变量导致的问题。
写在开始最近发现自己的CI服务器无法正常的编译 .NET 5.0 的程序了， 一开始以为是代码有问题， 后来发现问题没有这么简单。错误内容/app/TelegramSearchBot/TelegramSearchBot.csproj : error NU3037: Package 'System.Windows.Extensions 5.0.0' from source 'https://api.nuget.org/v3/index.json': The author primary signature validity period has expired. /app/TelegramSearchBot/TelegramSearchBot.csproj : error NU3028: Package 'System.Windows.Extensions 5.0.0' from source 'https://api.nuget.org/v3/index.json': The repository countersignature's timestamp found a chain building issue: UntrustedRoot: self signed certificate in certificate chain解决方法发现是 .NET 5.0 的Docker编译环境的CA出现了问题，把原来的镜像换成 mcr.microsoft.com/dotnet/sdk:5.0.102-ca-patch-buster-slim 问题就能解决了写在最后这个解决方法是在这里找到的：NuGet/Announcements#49 (comment)倒是没花多少时间，就是突然炸一下挺难受的，不知道啥时候能修好，感觉得改不少仓库的编译。。。
