Can not reinstall nouveau driver

Hi, I have have incorrectly used nvidia-installer-dkms without the BumbleBee flag -b (however I have a hybrid GPU system). This effectively broke my installation (boot ends up at a blinking underscore character).

I tried liveusb boot with chroot. Here I planned to again reinstall either nouveau or bumblebee directly. Now in this liveusb iam trying sudo nvidia-installer-dkms -n and it fails (also with -b). This is the output:

How could I fix this problem and install the nouveau drivers or bumblebee drivers when my computer doesnt boot?

Some ideas:

  • Are you sure you chrooted to the correct disk?
  • Have you updated your system before trying to install nouveau?

to check that you are chrooted take a look if your users home is present in filesystem:
cd /home
ls

As others have noted - seeing this tells me you likely didn’t chroot correctly.
