NU1101错误：无法找到Telerik试用版NuGet包求助排查

项目已配置含凭据的NuGet源，此前可正常获取依赖，但近期执行NuGet还原时出现NU1101错误，无法找到以下三个Telerik试用版包：

• Telerik.Drawing.Skia.Trial
• Telerik.Reporting.JsonSerialization.Trial
• Telerik.Reporting.WebServiceDataSource.Trial

该问题涉及Domain、Apis、Application等多个.csproj项目。已确认用户权限正常，切换至历史分支测试后问题仍存在，怀疑Telerik源故障但暂无其他开发者反馈，需协助定位问题。

排查建议 #

• 验证Telerik源包存在性：在本地执行nuget list Telerik.Drawing.Skia.Trial -Source telerikNugetV3，确认目标包是否存在于配置的源中；若返回空，说明源中无此包，可能是Telerik移除试用版包或源配置异常。
• 重新配置源凭据：执行nuget sources update -Name telerikNugetV3 -UserName <你的用户名> -Password <你的密钥>，避免凭据过期或配置错误导致的访问失败。
• 检查项目包版本约束：打开.csproj文件查看三个包的Version字段，确认是否指定了已被移除的特定版本；尝试改为通配符（如*）或确认Telerik当前提供的试用版版本号。
• 清理NuGet本地缓存：执行dotnet nuget locals all --clear，清除本地缓存后重新执行还原，排除缓存缺失导致的错误。
• 确认试用版包状态：登录Telerik账户查看试用版包下载页面，确认这三个包是否仍可获取；部分试用版包可能因试用期满下架，或合并至其他主包中。
