I cannot confirm, it seems to be still non-working for me.
I upgraded to systemd/260.1-1
$ apt policy systemd
systemd:
Installed: 260.1-1
Candidate: 260.1-1
Version table:
*** 260.1-1 800
800 http://deb.debian.org/debian testing/main amd64 Packages
500 http://deb.debian.org/debian unstable/main amd64 Packages
100 /var/lib/dpkg/status
and I think I restarted all the relevant services (at least all the
ones pointed out by 'checkrestart' and cups.socket, as well as
cups.service).
I even tried to:
# systemctl restart apparmor.service
Despite this, I still see a flood of:
kernel: audit: type=1400 audit(1774541912.429:560): apparmor="DENIED"
operation="open" class="file" profile="/usr/sbin/cupsd" name="/" pid=35304
comm="usb" requested_mask="r" denied_mask="r" fsuid=0 ouid=0
in '/var/log/kern.log' and the USB printer is not receiving any data
from the machine.
Is there anything else (I haven't tried to reboot) that should be restarted?
Thanks for any help you or anyone else can provide!
