After updating the graphics driver, I could not get into graphical mode. So I removed the nvidia and xserver packages, and now, when I run apt-get -f install, I get these error messages:

It is the Elementary OS Freya 0.4 x86_64. It all started when I wanted to install Unity 8, and later I "installed" package nvidia-304, although I had installed nvidia-340.

I think it does not matter now, because I do not have any of these packages.

I managed to remove the nvidia-prime package using these commands:

sudo mv /var/lib/dpkg/info/<packagename>.* /tmp/
sudo dpkg --removed --force-remove-reinstreq <packagename>
sudo apt-get remove <packagename>
sudo apt-get autoremove && sudo apt-get autoclean

But now I have a similar problem with a package libc-bin, when I want to install anything, which no longer I can not remove:

This seems to me like a grave error of dpkg. I do not know whether it would be best to re-install and configure the package manager. What do you think?

  • How did you update the graphics driver? If you're downloading from Nvidia's website, you're doing it wrong. I recommend performing a clean installation of Ubuntu and then running the command sudo apt install nvidia-current to install your graphics drivers. Jan 14 '17 at 3:08

    Of course, it is the Elementary OS. I updated my question about these and other informations.

  • I installed it through APT, like everything. I could re-install the system, but my cd-rom is dead, and my motherboard does not support USB boot.

  • So it is "of course" not Ubuntu. So it is off-topic.

  • Try sudo apt install --reinstall libc-bin Jan 14 '17 at 23:50
