The proper way to do this would be to fetch just the headers and extract the location field: $ URL="https://cran.r-project.org/package=httr&version=1.3.0"; $ curl -sI $URL | awk '/^Location:/{print $2}' https://cran.r-project.org/src/contrib/Archive/httr/httr_1.3.0.tar.gz But that's not the point. I'm talking about RPM packaging, and the point is, as I said, that the tool that expands and downloads sources from specfiles simply doesn't do that, because it can't trust an extension sent from a remote server. We need to provide it explicitly in the URL. -- Iñaki Úcar ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
