I have installed Ubuntu 17.10 and all software works fine. I made an update from 17.10 to 18.04 and it was successfully. I need to use Nvidia driver and CUDA for some deep learning projects. So some package are installed and other not. I follow some topics on the web and I modified /etc/apt/sources.list and from this modification, unfortunately, I typed wrong command that remove all Ubuntu features and software:
sudo apt-get autoremove
When I try update or upgrade or apt-get install -f, I get errors that package are corrupted , and i get differentes errors. I tried to use Ubuntu backup option from grub menu. I get desktop graphic of Ubuntu but when I tried to enter with my login and password I get this error:
failed to start session
How can I solve those errors?
