Hi Hadmut, and thanks for reporting this. Could you please paste the full journald audit log (`journald -t audit`)? I'd like to see if those AppArmor denials you are seeing are the only ones, or if there's more.
I cannot see any interface in snapd that would grant access to the "/sys/devices/pnp*" tree; but it might also be that these warnings are not fatal, and cura-slicer proceeds to do other operations? ** Changed in: snapd (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1950855 Title: Can't enable snap to print on a usb printer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1950855/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
