Just to mention that RPM Fusion is branched for f28
It means that you need to fetch the f28 branch in git and master now
point to f29
(same as in fedora).
The f29 buildroot isn't yet working, but it should be fixed in the coming hours.
Please hold your build until Tuesday, as the packages aren't all
pushed out of the infra yet.
The plan is to have all f28 packages signed, then push both rawhide
and branched repositories.
