By the end of the previous comment I had experienced a weird bug. But I decided to post it here as a separate comment because this is still relevant to this thread.
I resolved the issues by: 1. changing the default player 2. opening a PDF document that contains a link to a local video 3. clicking the link to the video (and failing to open) 4. closing evince and opening the same document again 5. clicking the link to the video again (and succeeding this time) I had to reproduce those steps for both totem and for vlc, ... but now, everything just works! After that initial hurdle, changing default players results in opening the correct default video player. I'm not really sure what happened, but the issue just fixed itself. There are still some odd messages in the kernel log (see attached file). I don't know if this is reproducible elsewhere, or if this bug should be marked as resolved or not, as I'm way past due to do a clean install of the newest Ubuntu: rolandog@computer:~$ lsb_release -rd Description: Ubuntu 20.10 Release: 20.10 rolandog@computer:~$ apt-cache policy evince evince: Installed: 3.38.0-1 Candidate: 3.38.0-1 Version table: *** 3.38.0-1 500 500 http://nl.archive.ubuntu.com/ubuntu groovy/main amd64 Packages 100 /var/lib/dpkg/status I hope this helps out someone getting unexpected behavior. ** Attachment added: "rolandog-apparmor-kernel-audit-2.txt" https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/462419/+attachment/5509157/+files/rolandog-apparmor-kernel-audit-2.txt -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to evince in Ubuntu. https://bugs.launchpad.net/bugs/462419 Title: evince apparmor profile prevents movies from opening To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/462419/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
