Hi Héctor,
Thank you for contacting Syncfusion Support,
We have analyzed the reported query (getting error while installing Syncfusion MVC Core in openSUSE 42.2 OS). And we found that the dotnet core support for openSUSE leap 42.2 is not provided yet. For more details to know about openSUSE 42.2 dotnet support, please refer the attached link and image
Please let us know if you need further assistance on this
Regards,
