Public bug reported: Ubuntu 25.04.
After last updates to apparmor, all AppImages stopped running, giving the message: $ ./filename.AppImage fusermount: mount failed: Permission denied Cannot mount AppImage, please check your FUSE setup. You might still be able to extract the contents of this AppImage if you run it with the --appimage-extract option.
