I'm facing a problem with installing Nvidia. I have tried many solutions but none of them is working. Even, I can not open the Software Updater.

enter image description here

#Python 3.7.4
#tensorflow-gpu 2.2.0

import tensorflow as tf


print("Num GPUs Available: ", len(tf.config.experimental.list_physical_devices('GPU')))

Num GPUs Available: 0

$lspci | grep -i --color 'vga\|3d\|2d'

01:00.0 VGA compatible controller: NVIDIA Corporation GP102 [GeForce GTX 1080 Ti] (rev a1)

$nvidia-smi

NVIDIA: could not open the device file /dev/nvidiactl (No such file or directory).
NVIDIA-SMI has failed because it couldn't communicate with NVIDIA driver. Make sure that latest NVIDIA driver is installed and running.

This is a list of all the problems that I face when I'm trying to install Nvidia and Cuda on Ubuntu 16.04.

$sudo apt-get purge nvidia*

...

I have tried many answers

$sudo -s -- <<EOF
sudo dpkg --configure -a
sudo apt install -f
sudo apt dist-upgrade
sudo apt autoremove --purge
sudo dpkg -i /var/cache/apt/archives/*.deb

$sudo -s -- <<EOF

But I got a different error and I also changed source.list file. In addition, I have removed the package from the state and I have tried synaptic

The first thing I would do is getting apt working again as detailed here:

To summarize the answer:

Visit http://packages.ubuntu.com, and download the python-minimal and python3-minimal and apt packages, then install those packages using dpkg. It may take a few iterations, as dpkg complains about other missing dependencies that you must download and install in the correct order.

Generally, most users who have broken or missing Python find it faster and easier to simply backup their data and do a clean-install.

  • The problem is that I have my work and my labmate work in this system and it needs more time to configure the system again. I faced many problems to find the compatible module with my work. I have tried sudo dpkg -i to download all modules one by one and it is not working. – I_Al-thamary Jan 20 '21 at 07:17
  • dpkg: error processing package python-minimal (--install): subprocess installed post-installation script returned error exit status 127 Processing triggers for man-db (2.7.5-1) ... Errors were encountered while processing: python-minimal – I_Al-thamary Jan 20 '21 at 08:07
  • I also use sudo dpkg -i --force-depends – I_Al-thamary Jan 20 '21 at 08:10
  • I can not enter the system any more. I will try to copy the hard drive. – I_Al-thamary Jan 20 '21 at 11:48
  • @i_thamary You should be able to boot with a Live USB and then see your files in /home directory of your broken partition. Then you can copy them off. No need to copy all the broken programs at this time... – WinEunuuchs2Unix Jan 20 '21 at 12:22
  • I will try it thank you. – I_Al-thamary Jan 20 '21 at 12:53
