I found the cause of the bug and would like to propose a fix. The AppArmor profile for Evince contains a specific clause to handle saving files that looks like this:
# evince creates a temporary stream file like '.goutputstream-XXXXXX' in the # directory a file is saved. This allows that behavior. owner /**/.goutputstream-* w, However, write permission is not sufficient to rename a file - the permission should be write AND read: owner /**/.goutputstream-* rw, Making this change has fixed the problem. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to evince in Ubuntu. https://bugs.launchpad.net/bugs/1567565 Title: Permission error saving a file Status in evince package in Ubuntu: New Bug description: On Ubuntu 15.10, using evince 3.16.1-0ubuntu1, I fill out a PDF form. When I save the form, I get the message "Error renaming temporary file: Permission denied", and the file is not saved. I don't have permissions trouble in any other apps. The problem happens only when I'm using a cryptsetup ext4 filesystem that I mount in /mnt, and not for example in my home directory or in /tmp. Although I launch evince from the terminal, there are no unusual error messages printed there. However, journalctl shows a string of error messages (see attached log).
