By using the original /usr/share/applications/apkd-mime-handler.desktop the app can be installed by means of the file browser from ichtyosaurus. Using
[X-Sailjail]
Disabled
in apkd-mime-handler.desktop as the release notes ([Release notes] Vanha Rauma 4.4.0) recommend, does NOT work!
The app can be installed without an error, but unfortunately the app does not start. There is only a black window on the home screen, which won’t open.
The app consists of four apk files, one main file and three config files. Does such a kind of app have to be handled differently on installation?
