I’m using the latest lubuntu version (it is like Ubuntu 17, but uses lightweight LXDE window manager instead of Gnome). I installed the latest nitrokey-app and the tray icon works fine. Other functions work fine as far as I can tell, but nothing happens when I click configure. Literally nothing at all. No debug messages (even after increasing the level to 4), no errors. Nothing.
Please let me know if I can do anything else to troubleshoot this, or alternatively if there is any other method to configure a hidden volume.
