This question already has an answer here:
I am new to Debian and I want to install the nvidia cuda toolkit, so I typed:
apt install nvidia-cuda-toolkit
but it did not work, I found out I need to add a source in /etc/apt/sources.list which contains this cuda package.
However, as for now there are only a few lines in /etc/apt/sources.list referring to a university, which I chose during installation.
I do not know how to find out which source I need to add.
Is there a debian database, where I can submit the program I need and which in turn gives me a list of sources containing it?
