Title:
cups-pdf blocked by apparmor
Status in cups package in Ubuntu:
Expired
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.

What happened:
cups-pdf when installed for the first time fails with the following apparmor
denials:
[ 6117.686934] audit: type=1400 audit(1497816878.998:1079): apparmor="DENIED"

What I expected to happen:
cups-pdf creates the pdf file it was supposed to.
As a workaround, I set cups-pdf to use the third-party settings from the cups
profile, then it worked as expected.
