I have a LUKS encrypted USB disk. When I plug it in, it should mount it and ask me for the password. It asks me for the password which I type in, but the dialog never goes away if I hit Cancel or Enter. The only way to make it go away is to physically remove the USB drive.

After I remove it, it asks me for the password again, and the same problem occurs. So I remove it again. But it never decrypts and mounts the drive. So I basically cant use it anymore.

It works fine on my Manjaro KDE: with dolphin, thunar and nautilus. This behavior only happens in Ubuntu and nautilus.
