As instruções para instalar o CUDA Toolkit (11.5) no Debian (11) estão bem organizadas aqui:desenvolvedor.nvidia.com/cuda-downloads.
Mas pareço ter um pequeno problema de dependência, quer eu tente o método deb (local) ou o método deb (rede). Minha impressão é que aptdeseja instalar as 470versões dos pacotes relacionados à nvidia, mas deveria instalar as 495versões.
Se eu correr sudo apt install cuda, obtenho:
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
Consegui instalar algumas dependências especificando a versão manualmente, por exemplo, sudo apt install nvidia-settings=495.29.05-1mas isso parece um processo interminável.
Nota: Se eu executar sudo apt-cache policy nvidia-driver, obtenho:
nvidia-driver:
Installed: (none)
Candidate: 470.74-1

Alguém sabe como devo proceder?
No momento meu /etc/apt/sources.list é o seguinte:

PS: Também tentei o método "runfile (local)", mas depois de executar sudo sh cuda_11.5.0_495.29.05_linux.rune selecionar os componentes a serem instalados, recebo "Falha na instalação" sem mais detalhes.

Enfrentei esse problema no Debian 12 (testes). Eu consertei baixando o .deb para liburcu6 em https://packages.debian.org/bullseye/liburcu6 e instalá-lo com
sudo apt install ./Downloads/liburcu6_0.12.2-1_amd64.deb
Depois disso, a reexecução sudo apt-get -y install cudafuncionou bem. Não mergulhei mais profundamente para ver por que as versões mais recentes do Debian não incluem liburcu6 nelas.

Saia xserverantes de executar a instalação para que a nvidia-driverinstalação não falhe.
sudo service lightdm stop
faria isso.

Tenho o mesmo problema, mas com a versão recente 510.39.01 e cuda 11-6;
/var/cuda-repo-debian11-11-6-local# dpkg -i nvidia-libopencl1_510.39.01-1_amd64.deb
Selecting previously unselected package nvidia-libopencl1:amd64.
dpkg: regarding nvidia-libopencl1_510.39.01-1_amd64.deb containing nvidia-libopencl1:amd64:
nvidia-libopencl1 conflicts with libopencl1
ocl-icd-libopencl1:amd64 provides libopencl1 and is present and installed.
dpkg: error processing archive nvidia-libopencl1_510.39.01-1_amd64.deb (--install):
conflicting packages - not installing nvidia-libopencl1:amd64
Errors were encountered while processing:

# dpkg -l | grep liburcu6
ii liburcu6:amd64 0.12.2-1 amd64 userspace RCU (read-copy-update) library
Claro que se eu tentar remover ocl-icd-libopencl1, tenho cerca de 50 pacotes que dependem disso. Acho que Vincent já havia trabalhado nesse bug debian #755513, mas isso pode ser um problema novo.

Eu consertei baixando o .deb para liburcu6 emhttps://packages.debian.org/bullseye/liburcu6e instalá-lo com
sudo apt install ./Downloads/liburcu6_0.12.2-1_amd64.deb

Preciso de um para AMD64 (CPUs Intel também usam essa arquitetura). O que posso fazer?
