Control: tags -1 moreinfo Control: owner -1 ! Hi, unfortunately you can't tweak the orig tarball like that. I didn't notice the issue, now you have two solutions: use the tarball from here 1) https://packages.debian.org/source/unstable/clblas and extract patches with dpkg-sources 2) use a fake import of the correct upstream tarball (you need to tweak the orig source version) cheers, G.
