[opensuse-buildservice] 13556 packages suddenly changed to unresovable?

Hi! All packages in d:l:R:autoCran turned to state unresolvable because there is choice :-) :-( unresolvable: have choice for xorg-x11-fonts-100dpi needed by R-base: xorg-x11-fonts xorg-x11-fonts-legacy have choice for xorg-x11-fonts-75dpi needed by R-base: xorg-x11-fonts xorg-x11-fonts-legacy have choice for python3 needed by texlive-filesystem: python3 python38 Is this temporarily or will this persist? Do I need to recreate 13556 spec files or not? In case this change is here to stay: How could I have known? How could I have found out beforehand, that such a change is imminent? Where can I read what I have to do now to make the packages build again? All the best Detlef
