Ошибка! Настройки конфигурации по умолчанию системы управления питанием Gnome ...

1. The way to avoid this problem is to keep enough disk space for system.

2. If you already have it just do:

 ctr-alt-f1 (or f2)
 sudo apt-get autoclean
 sudo apt-get autoremove
 sudo reboot
 

First one removes local repository, the second one removes depended packeges if they not need

3. If it didn`t help then unistall some application or files you don`t need

  sudo apt-get remove something_large
  sudo rm something_large
  sudo apt-get autoremove
  sudo reboot

4. If you can`t enter to terminal, first enter your password in unworking window that you usually use to enter gnome, after that you can use step 1
