Hello, I'm trying to install Ubuntu 12.04 LTS into VirtualBox 4.18 running on a Debian machine. I've got so far as a screen with the timezone selection, but 3 hours passed since then, and all I see is a spinning cursor and no progress in copying files. No error messages (at least not through the GUI) have been given. The GUI is overall responsive (I can move the window having the installation, move the mouse pointer etc.) but the installation seems to make no progress. It shouldn't take this long, should it?
