today I installed ubuntu from website (actually I want to try deepin at first , but after my installing, I cant't enter the system, so I installed ubuntu.)

I will recor some problems and solution that I have faced while my using.

first problem: the software is empty.

solution: click the desktop , press : ctrl+alt+t, key in : sudo apt update;

                                                                                    sudo apt upgrade;

                                                                                    sudo systemctl reboot;
