-- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1698693 Title: cups-pdf blocked by apparmor Status in cups package in Ubuntu: Incomplete Bug description: cups-pdf cannot create the ~/PDF directory if it does not exist and fails with no indication to the user. It should however be pointed out that cups-pdf allows the system administrator to change it's output directory by changing the Out key in /etc/cups/cups-pdf.conf. As such apparmor will get in the way again if the admin changes the Out key to some other location outside of the ${HOME}/PDF directory. (It's default setting.) cups-pdf also does not have an #include for using local overrides in it's apparmor config. As such any fixes that the local admin makes will be overwritten by the next update to the cups package, breaking it again.

As a workaround, I set cups-pdf to use the third-party settings from the cups profile, then it worked as expected. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 CupsErrorLog: Error: [Errno 13] Permission denied: '/var/log/cups/error_log' CurrentDesktop: MATE DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2017-11-24 (281 days ago) InstallationMedia: Ubuntu-MATE 17.10 "Artful Aardvark" - Release amd64 (20171018) Lpstat: device for EPSONET-4550: ipp://call.codenet.local:631/printers/EPSON_ET-4550_Series device for PDF: cups-pdf:/ MachineType: Gigabyte Technology Co., Ltd.
