[Bug 1915910] Re: evince does not print (apparmor, pxgsettings)

[Brian Murray]

Hello Togo28, or anyone else affected,

Accepted evince into jammy-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/evince/42.3-0ubuntu3
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

  evince does not print (apparmor, pxgsettings)

Bug description:
  * Impact

  Evince hangs when opening the printing dialog for some users with a
  remote printer configured and connected

  * Test case

  - configure a remote printer and turn it on
  - open a pdf
  - try to print the document

  the print dialog shouldn't freeze the viewer

  * What could go wrong

  The change is only allowing access to one extra system binary from the
  apparmor profile so shouldn't really have an impact on the software
  behaviour. If the syntax or content of the change was incorrect it
  could make the apparmor profile not been loaded anymore or block
  access to thing that should be allowed, so ensure that opening
  documents, printing and thumbnailing are still working

  audit: type=1400 audit(1613557537.646:81): apparmor="DENIED" operation="exec" profile="/usr/bin/evince" name="/usr/lib/x86_64-linux-gnu/libproxy/0.4.17/pxgsettings" pid=3500 comm="sh" requested_mask="x" denied_mask="x" fsuid=1000 ouid=0

  It seems that evince has no rights to print if I understand this
  correctly

  Printing the same pdf-file from the same origin/folder works with
  OCULAR

  The error is reproduceable
