Comment Summary: ---------------- suggested fix: make libnvidia-ml-dev depend on: libnvidia-compute-450 (>= 450) | libnvidia-compute-450-server (>= 450) | libnvidia-ml.so.1 (>= 450) | libnvidia-ml1 (>=450) instead of: libnvidia-compute-450 (>= 450) | libnvidia-compute-450-server (>= 450) | libnvidia-ml.so.1 (>= 450)
Longer version :) ----------------- I noticed now that libnvidia-ml.so.1 (>= 450) would satisfy libnvidia-ml-dev's dependencies (and in turn, would allow the installation of nvidia-cuda-toolkit). both libnvidia-compute-450 and libnvidia-compute-455 provide libnvidia-ml1, AND contain the file libnvidia-ml.so.1, but do not "provide" libnvidia-ml.so.1, which suggests the problem is only in the dependency *declerations*, and nothing "material" prevents the installation of these packages together (i.e. if we would force their installation, they would work). If this is correct, I believe that changing libnvidia-ml-dev to depend on libnvidia-ml1 (>=450) as an alternative to the dependency on libnvidia-ml.so.1 would fix the problem. To test this theory, I created a dummy package (using equivs) that contain no files, depends on libnvidia-ml1 (>= 455.28) and "provides" libnvidia-ml.so.1 (= 455.28). After installing this package, I successfully installed nvidia-cuda-toolkit along with nvidia-driver-455. This setup works for me: I was able to install pytorch and train some models on the gpu (verified using nvidia-smi). ** Attachment added: "equiv control file of the dummy package I created" https://bugs.launchpad.net/ubuntu/+source/nvidia-cuda-toolkit/+bug/1900627/+attachment/5424775/+files/libnvidia-ml-dummy.equivs -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1900627 Title: installing nvidia-cuda-toolkit removes nvidia-driver-455 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-cuda-toolkit/+bug/1900627/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
