NuGet install-package error (unable to find version that is compatible)

I'm trying to install Xamarin.Forms package, however, the console throws this error

Install-Package : Unable to find a version of 'Xamarin.Android.Support.Design' that is compatible with 'Acr.UserDialogs 6.3.8 constraint: Xamarin.Android.Support.Design (>= 23.3.0 && < 26.0.0)', 'Xamarin.Forms 2.4.0.282 constraint: Xamarin.Android.Support.Design (= 23.3.0)'.At line:1 char:1+ Install-Package Xamarin.Forms+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+ CategoryInfo          : NotSpecified: (:) [Install-Package], Exception+ FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PackageManagement.PowerShellCmdlets.InstallPackageCommand

I understand that some packages aren't compatible, I tried to install them individually, tried to changed the target API level, nothing.

So my question is, how can I install Xamarin.Forms inside the package manager terminal without getting those errors?

I'm new to Android development in Xamarin.
