[R-sig-Debian] rkward_0.6.5-1~stretchcran.0_amd64.deb missing

[Griera]

Hi:

I have tried to upgrade from version 3.4.0 to 3.4.1 in a Debian Stretch following the instructions of the web page:

  https://cran.r-project.org/bin/linux/debian/

but after updating, Rkward does not work (Error in RK: Graphics API version mismatch). Analyzing the problem, I notice that the Rkward package is not available in the amd64 version (yes in the i386 version), for example here:

  https://cran.r-project.org/bin/linux/debian/stretch-cran34/

It is not necessary? Can anyone help me on how can I solve the
problem that Rkward does not work?

Thanks a lot. Griera
