I've moved this bug to the udftools project, as I suspect it may be an issue with that package interacting with apparmor, based on the lines you sent in your most recent message:
> [ 34.919704] audit: type=1400 audit(1739919236.502:288): apparmor="DENIED" operation="mknod" class="file" profile="/usr/bin/wsdd" name="/usr/lib/python3/dist-packages/defusedxml/__pycache__/__init__.cpython-313.pyc.124069992405296" pid=4943 comm="python3" requested_mask="c" denied_mask="c" fsuid=1000 ouid=1000 If possible, try to find the most recent version of the kernel/packages that this worked, which will give you a starting point on finding the version which broke things. The maintainers of udftools should be able to help more or point you in the right direction. ** Package changed: linux (Ubuntu) => udftools (Ubuntu) ** Also affects: udftools (Ubuntu Noble) Importance: Undecided Status: New ** Changed in: udftools (Ubuntu) Assignee: Benjamin Wheeler (benjaminwheeler) => (unassigned) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2098552 Title: .Cannot mount usb DVD with blank disc To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udftools/+bug/2098552/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
