I’m using AppArmor with the Testing Repo as per the Whonix wiki.
Gwenview and Okular can be opened no problem, but AppArmor blocks the programs from opening images. I’ve tested it a bit and I have found that the only way to view images with these programs is to transfer the image to the desktop. If the image file is on the desktop, it can be opened. However, if the images are in a directory on the desktop, they cannot be opened.
How to reproduce:
Install KVM Whonix with Testing Repo and AppArmor as described in the wiki. Download any image with Tor Browser to Tor Browser’s downloads directory. Try to open the image with Okular or Gwenview. It fails with an AppArmor notification appearing. Now try transferring the image to the desktop and opening it. It works. Now create a directory on the desktop and transfer the image to that. Try opening it. It fails.
I imagine that this is a bug, right?
I’ve personally just disabled the AppArmor profiles for Gwenview and Okular, since I have no idea how to edit profiles.
