I do not understand why, but the second time I lauched an install using Ubuntu Desktop amd64 ISO http://cdimage.ubuntu.com/daily-live/20130113/raring-desktop-amd64.iso I did not have problems writing the timezone city using the keyboard, so this problem may not always occur.
Up to now I do not understand what triggers the problem.
