OK, thanks. At the top of history.log.1 you have: Upgrade: ... nvidia-libopencl1:amd64 (340.46-1, 340.46-3) ... which results in the installation of a pile of nvidia stuff. I'm not sure why you would gain the other nvidia stuff at that point if you didn't have it already, because debdiff says nvidia-libopencl1_340.46-1_amd64.deb and nvidia-libopencl1_340.46-3_amd64.deb (from snapshot.debian.org) have identical metadata apart from version number and Installed-Size. however, nvidia-libopencl1_340.46-3_amd64.deb does have Recommends: nvidia-opencl-icd | opencl-icd so that would maybe explain it. Recursively following Depends and Recommends from nvidia-opencl-icd pulls in the whole nvidia stack. Next question, why did you have nvidia-opencl-icd in the first place? I suspect the answer is probably https://bugs.debian.org/739176 which has already been fixed. S -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
