Okay it seems to work with url encoded + signs, but the links viewing in the http are wrong. However, I am currently getting stuck trying to build and the build framework does not appear to be able to find the package.
running make build in packages/libsolv I am getting:
This is due to a backend change of our infrastructure. We may run into other issues here that we didnāt predict - Iāve pinged folks for a solutionā¦
I am still seeing the issue with rpms containing ā+ā characters failing to download, so the workaround described on the mailing list is needed at the moment.
EDIT: Use the thread @puneetse linked to above to track the issue. (I originally thought it was a direct link to the mailing list announcement, not an indirect link via a separate thread.)
Yeah it was a back end change, nothing specific to the release, they just happened to do it on when that specific release came out. Actually all the releases were broke at the time. They have updated the servers to deal with special characters. It should be working now, as attested by the whole thread.
