The apparmor changes brought some minor improvement, now there's no more apparmor messages at all from the cura snap.
I am somewhat familiar with AppArmor, but wasn't aware that there are files for editing. I thought the apparmor profiles are dynamically created by snapd when starting a snap. It obviously finds the printer, otherwise it wouldn't offer to print via USB. It, however, still doesn't print and still not updates it's status widget, so it's still hung, but no error messages anymore. Is there some documentation about how to debug and trace snap binaries? -- 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
