Hi, I am having trouble installing CUDA 11.2 according to these instructions and this download. After following all the Pre-installation Actions, followed by the Package Manager Installtion for Ubuntu (chapter 3.8), I get the following error after running: $ sudo apt-get -y install cuda INFO:Enable nvidia DEBUG:Parsing /usr/share/ubuntu-drivers-common/quirks/put_your_quirks_here DEBUG:Parsing /usr/share/ubuntu-drivers-common/quirks/lenovo_thinkpad DEBUG:Parsing /usr/share/ubuntu-drivers-common/quirks/dell_latitude Loading new nvidia-460.32.03 DKMS files...

@bob18 How did you downgrade the kernel?

hi @edouard1, I used the following article, it was very easy! The ubuntu installation I used came with kernel 5.8, which is the one I am working with right now.

@rob18 Which Linux Kernel are you using now? I’m facing the same problem but with CUDA 11.3 on Ubuntu 20.04

Having trouble installing CUDA 11.2 on Ubuntu20.04 (kernel 5.11.5). Nvidia driver unsupported?

Update: doing a kernel downgrade solved the problem effortlessly!
