The problem arised when i tried to uninstall the cuda-10.0 toolkit from my system using the following method mentioned in this thread by user271219.

1) My Nvidia driver

$ cat /proc/driver/nvidia/version



NVRM version: NVIDIA UNIX x86_64 Kernel Module  387.26  Thu Nov  2 21:20:16 PDT 2017

GCC version:  gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.9)

2) Trying to remove cuda-10-0

$ sudo apt-get purge cuda-10-0 



You might want to run 'apt-get -f install' to correct these:

The following packages have unmet dependencies:

 cuda-cudart-dev-10-0 : Depends: cuda-driver-dev-10-0 (>= 10.0.130) but it is not going to be installed

 cuda-libraries-dev-10-0 : Depends: cuda-driver-dev-10-0 (>= 10.0.130) but it is not going to be installed

 cuda-samples-10-0 : Depends: cuda-driver-dev-10-0 but it is not going to be installed

 cuda-toolkit-10-0 : Depends: cuda-nvml-dev-10-0 (>= 10.0.130) but it is not going to be installed

 cuda-visual-tools-10-0 : Depends: cuda-driver-dev-10-0 (>= 10.0.130) but it is not going to be installed

                          Depends: cuda-nvml-dev-10-0 (>= 10.0.130) but it is not going to be installed

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

3) Forcing the apt-get

$ sudo apt-get install -f



The following additional packages will be installed:

  cuda-driver-dev-10-0 cuda-nvml-dev-10-0

The following NEW packages will be installed:

  cuda-driver-dev-10-0 cuda-nvml-dev-10-0

I want to get my system clean from the current cuda files and reinstall it.

I deleted the repositories related to cuda

$ rm /etc/apt/sources.list.d/cuda*

updated the repositories using apt-get update

Purged all the files related to cuda

$ sudo apt-get --purge remove cuda*

$ sudo apt-get autoremove

Problem solved.
