Status in linux package in Ubuntu: Confirmed Bug description: Hello, In a pdf (created with Libre Office, URL checked and working), when I try to open a URL (including the one in "About Evince" to the Website), it doesn't work and the following message appears : Failed to launch preferred application for category WebBrowser. Failed to execute child process "/usr/lib/x86_64-linux-gnu/xfce4/exo-1/exo- helper-2" (Permission denied) I reported this bug to Evince (https://gitlab.gnome.org/GNOME/evince/-/issues/1539#note_999642) and someone told me : "The issue you describe is likely a constraint defined at the system level, for example, using AppArmor. The issue should be reported to the distribution."
