"pacman -Syu" not possible

[klassikmann]

I'm using rAudio-1 on a RPi 3B, architecture: aarch64. I'm quite satisfied with this configuration.
Today a "pacman -Syu" was not successful:

rAudio:~  #  pacman -Syu
:: Synchronizing package databases...
error: failed retrieving file '+R.db' from rern.github.io : The requested URL returned error: 404
error: failed to update +R (failed to retrieve some files)
....
error: failed to synchronize all databases

Observation:
https://github.com/rern/rern.github.io/blob/master/aarch64/%2BR.db is linked to "IntxLNK�+R.db.tar.xz" (Interix style).
