Daear @generix, per this thread in which you helped me extensively, I ended up upgrading the nvidia driver on my Ubuntu 18.04 workstation to version 510: Black screen in Ubuntu 18 even after purging Nvidia and installing drivers from repository - #34 by generix
I hadn’t reinstalled cuda because I could compartmentalize it in conda environments for all applications I needed so far.
Now I needed to install cuda for an application that seemingly cannot be in a conda environment. I mistakenly installed cudatoolkit 11.2 (which the application recommended) following the instructions for “deb local” on the nvidia website.
I got an incompatibility issue and thus remove it with:
sudo apt-get --purge remove "*cublas*" "cuda*" "nsight*"
And
sudo rm -rf /usr/local/cuda*
I learned nvidia driver v 510 requires toolkit 11.6, but in trying to install it per instructions here https://developer.nvidia.com/cuda-11-6-0-download-archive?target_os=Linux&target_arch=x86_64&Distribution=Ubuntu&target_version=18.04&target_type=deb_local.
I got a broken packages error:
The following packages have unmet dependencies:
cuda : Depends: cuda-11-6 (>= 11.6.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I do not seem to have any nivida related repo to comment out in
sudo vim /etc/apt/sources.list
(Attaching file here just in case I missed anything relevant
jgalaz_ubuntu18_sources.txt (2.9 KB)
)
The following after uninstalling cuda 11.2 and before attempting installation of cuda 11.6 did not seem to help:
sudo apt --fix-broken install
sudo apt-get autoremove
Autoremove output (below) suggested that driver 460 was still installed on my machine (weird, as previously nvidia-smi output indicated 510 was the driver, as per the thread linked at the beginning of this thread).
Not sure what the issue is . Do I need a fresh terminal after removing a cuda version and installing a new one? Is rebooting required at any point? I’m a bit jaded with nvidia driver and cuda installations and am wary about tinkering with this more without advice.
Particularly perturbed that nvidia-smi isn’t working now, which might suggest that the nvidia driver is again messed up.
I work remotely so this is very stressful.
sudo apt-get autoremove
