/sourceware1/cygwin-staging/setup/upset: Error. Parsing failed. - duplicate packages "lapack" detected - x86_64/release/lapack/lapack vs. /var/ftp/pub/cygwin/x86_64/release/lapack Marco you created an additional lapack directory with duplicate files. I'd appreciate it if you would use the new upload mechanism since it will guard against this kind of thing. cgf
