issues after installing cuda 10....

Graphics / Linux Linux
1

I am not sure where to ask this question or even if it is a cuda 10 issue but maybe you can help me find out where to post it.

When I tried to update recently on ubuntu16 GTX1060 I get the following conflict…

sudo apt-get install -f

Unpacking libcublas-dev (10.1.0.105-1) …
dpkg: error processing archive /var/cache/apt/archives/libcublas-dev_10.1.0.105-1_amd64.deb (–unpack):
trying to overwrite ‘/usr/lib/x86_64-linux-gnu/stubs/libcublas.so’, which is also in package nvidia-cuda-dev 7.5.18-0ubuntu1
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

How can I get around this error?

Here is some additional data:

Telling by the errors, you would have to uninstall cuda 7.5 first.

I seem to be unable to uninstall … any help appreciated.

sudo apt-get install -f

maybe
sudo apt-get remove --purge nvidia-cuda*

yes…I did a sudo apt-get remove and that seemed to resolve the issue. I did not do a purge nivdia-cuda*

Even I encountered the same issue. I resolved it using the following steps:

You will see this line in your error…

trying to overwrite '/usr/lib/x86_64-linux-gnu/stubs/libcublas.so', which is also in package nvidia-cuda-dev 7.5.18-0ubuntu1

This means that the /usr/lib/x86_64-linux-gnu/stubs/libcublas.so is already present and cannot be overwritten by dpkg.

I tried these commands to fix the issue. (WARNING: The older libcublas.so will be replaced by new libcublas.so… It may affect your environment…)

sudo dpkg -i --force-overwrite /var/cache/apt/archives/libcublas-dev_10.1.0.105-1_amd64.deb
sudo apt-get -f install

Preferably remove unwanted files after this by running

sudo apt autoremove
