Whenever I am trying to install something, I get the following error:

The following packages have unmet dependencies:



cuda-samples-8.0 : Depends: cuda-cufft-dev-8-0 but it is not going to be installed



cuda-toolkit-8.0 : Depends: cuda-cufft-dev-8-0 but it is not going to be installed



cuda-visual-tools-8.0 : Depends: cuda-cufft-dev-8-0 but it is not going to be installed

I try sudo apt-get -f install and it says:

The following packages were automatically installed and are no longer required:

[lots of cuda 7.5 packages and some other linux ones like linux-image-4.2.0-27-generic]

The following extra packages will be installed:

cuda-cufft-dev-8-0

The following NEW packages will be installed:

cuda-cufft-dev-8-0



Do you want to continue?

I tell it to continue and I get this error:

(Reading database ... 731426 files and directories currently installed.)

Preparing to unpack .../cuda-cufft-dev-8-0_8.0.61-1_amd64.deb ...

I tried to fix this for a while but couldn't so eventually I just started trying to uninstall cuda. In /usr/local/ I see cuda, cuda-7.5, and cuda-8.0 (which probably isn't good). I go to all the directories looking for unstalling files (/usr/local/cuda-6.5/bin/uninstall_cuda_7.5.pl) but I don't see any.

I would prefer to upgrade to the latest but at this point I'd be happy with uninstalling it too. What should I try next?

When I run sudo dpkg --configure -a I get:

dpkg: dependency problems prevent configuration of cuda-toolkit-8-0:

I just needed to clean my cache. This is what ended up working:

sudo dpkg --configure -a



sudo apt-get clean

After Cleaning cache, you can try these,

1. dpkg -l | grep cuda- | awk '{print $2}' | xargs -n1 sudo dpkg --purge


2. df -h


3. sudo apt-get purge nvidia*


4. sudo apt-get -f install


5. sudo apt autoremove

Hope, this might help you. Cheers
