Hello everyone.
I've read the whole thread and I am experiencing a related bug.
My specific scenario is that I'm creating a PDF (by exporting from Emacs
/ Org-Mode) that contains a link to a local video. It may have been a
recent change in an AppArmor that has resulted in the videos not opening
anymore (or maybe a security patch?), but I'm not able to open either
mp4 or webm videos like I could with mpv.
I read the /etc/apparmor.d/abstractions/evince file, and added the
following to the /etc/apparmor.d/local/usr.bin.evince file:
# vim:syntax=apparmor
#
# abstraction used by evince binaries
#
# supported archivers
/usr/bin/mpv ixr,
/usr/bin/totem ixr,
/usr/bin/vlc ixr,
After performing:
rolandog@computer:~$ sudo apparmor_parser --reload
/etc/apparmor.d/usr.bin.evince
I get the following error:
profile /usr/bin/evince: has merged rule /usr/bin/totem with conflicting x
modifiers
ERROR merging rules for profile /usr/bin/evince, failed to load
Playback with mpv (the player I had set as default) still doesn't work
(is blocked by AppArmor), and, after running the following command, I
get the messages shown in the attached file:
rolandog@computer:~$ grep audit /var/log/kern.log
After removing the totem line I get a similar error, but for vlc. After
removing both the totem line and the vlc line, I don't get an error (and
I can launch mpv (the default I had set).
However, I'm torn because this worked for me, but there may be others
that may have similar use-cases to mine that would prefer other players.
