I do not have a journald command on my ubuntu 20.04 system. apt-file search journald | fgrep /bin/ reports nothing, so it doesn't seem to be installable.
There is a /lib/systemd/systemd-journald but it doesn't take arguments: /lib/systemd/systemd-journald -t audit This program takes one or no arguments. Instead, I made a dmesg | grep cura-slicer , see attached. The author of the snap has recently added the raw-usb connection. Since then, cura-slicer offers the option to print to a usb printer, but then it goes into an endless loop, each causing one of these apparmor messages. The printer itself doesn't show any reaction, as if it did not receive any command. When using the regular (but older) cura debian package (i.e. not a snap), than the printer immediately starts heating the nozzle. ** Attachment added: "dmesg | grep cura-slicer" https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1950855/+attachment/5540987/+files/curalog -- 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
