Ubuntu Linux上的dotnet核心使用asp.net MVC和EF MySQL错误NU1001：无法恢复MySql.Data.EntityFrameworkCore

我已经构建了一个简单，扁平的dotnet核心MVC应用程序，我希望看到它在Linux上运行 . 它使用EF从mysql表中提取一些记录并在视图中显示它们 . 这一切都在我的主机（Win10）上构建和运行，但不会在Ubuntu VM中旋转以进行测试

在我执行“dotnet restore”后，“dotnet build”或“dotnet run”出现以下错误：

项目CoreCrossPlatformFlat（.NETCoreApp，Version = v1.0）将被编译，因为自上次构建以来，CLI的版本或位数发生了变化，为.NETCoreApp编译CoreCrossPlatformFlat，版本= v1.0 / opt / dotnet / corecrossplatform / src / CoreCrossPlatformFlat /project.json(25,52）：错误NU1001：无法解析依赖项MySql.Data.EntityFrameworkCore> = 7.0.4-IR-191 . 编译失败 . 0警告1错误

仅供参考：这是“dotnet --info”报道的内容：

对于VM，我按照以下说明操作：
