When I try to open any epub via Foliate (installed from official Ubuntu repositories), it does not run.
```
foliate Alcott, Louisa May - Little Women.epub
(com.github.johnfactotum.Foliate:2289): Gtk-WARNING **: 01:51:13.769: Unknown key gtk-modules in /home/archisman/.config/gtk-4.0/settings.ini

A workaround (https:/ /github. com/johnfactotu m/foliate/ issues/ 1271#issuecomme nt-2016575770) is to create the `/etc/apparmor. d/foliate` file with the appropriate content described in that link.
A similar bug was reported for VSCode (https:/ /bugs.launchpad .net/ubuntu/ +source/ apparmor/ +bug/2056517)
