1. The way to avoid this problem is to keep enough disk space for the 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 packages if they not needed
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 get to the terminal, first enter your password in unworking window which you usually use to enter gnome, after that you can use step 1
