On Ubuntu 24.04, while building UnrealEngine 5.4.4, and after running GenerateProjectFiles.sh, I get an error relating to the UnrealBuildTool, and a missing Microsoft NuGet Extension (Microsoft.Extensions.Configuration.Binder). (I also tried UnrealEngine 5.4.3 with the same result.) The full output is shown below. The microsoft.extensions.configuration.binder.6.0.0.nupkg file reported is indeed not in the directory (i.e. ~/.nuget/packages/microsoft.extensions.configuration.binder/6.0.0); though .nuspec and 6.0.0.nupkg.sha512 files are there. Any suggestions on how to get past this?
