I'm getting a similar error when clicking a hyperlink in a PDF document. An error ribbon appears:
Unable to open external link Failed to execute child process “/usr/lib/x86_64-linux-gnu/glib-2.0/gio-launch-desktop” (Permission denied) ** Changed in: evince (Ubuntu) Status: New => Confirmed ** Changed in: evince (Ubuntu) Importance: Undecided => High -- 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/1792648 Title: Can't preview document in evince - Ubuntu 18.10 Failed to execute child process (Permission Denied) Status in apparmor package in Ubuntu: New Status in evince package in Ubuntu: Confirmed Bug description: Ubuntu 18.10 Evince of a PDF Clicking PREVIEW I get busy awhile then Failed to print document Failed to execute child process "/usr/lib/x86_64-linux-gnu/glib-2.0/gio-launch-desktop" (Permissions denied) -- I looked at this only because of https://community.ubuntu.com/t /failed-to-preview-print/7956 where a user "flaviosm" reported the same thing.

I don't know if this applies to "flaviosm" too.. I can connect & test after printer is setup if deemed helpful (headcold - so no motivation currently) Filed online as unsuccessful via via `ubuntu-bug` on actual box..
