Sirs, First of all, thankyou very much for your effort. You are helping many people, like me, to discover all the possibilities of the Linux operating system.
Nevertheless I have found a serious issue. I'm installing your operating system on a virtual machine running on Windows 10. The virtualisation software that I use is Oracle's VM Virtualbox. I've dowloaded the .iso files (both the full installation, 3 DVDs, and the netinst versions) with identical results, using two different computers. In all cases I have installed the virtual machine using the ISO, using standard options, one drive (plus swap), root password, and user password. It install flawlessly the operating system, until I open the Konsole terminal and try to use the root privilegies. First I get mad trying to make it works, unsuccessfully. Then I supposed that I've typed my password wrong, or an issue with my keyboard layout... to summarize it was my fault. In order to avoid the same problem, I made another virtual machine, with identical results. I couldn't reach root (I had taken a photograph of my password and it was correct). The user could log in without any trouble. I've tried to reset root password through GRUB, without success. Finally I make it work by NOT assigning ANY password to root. Then my user is added to suddoers group (I suppose), and then I assing root a password with the order PASSWD. I have been searching through the Internet, and it looks this issue started with Debian 9 distribution. Hope this may help you to find and repair this annoying bug. For someone like me, who doesn't have any idea about linux this is a major problem. Again thank you, and good luck looking for the gap. Best regards, José Ramón Sánchez Gómez
