CUDA 11.7 Fails to Install

[Exkalamity]

Describe the bug
CUDA 11.7 cannot be installed because it fails at public GPG step in the installation guidelines outlined in https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#ubuntu-installation

To Reproduce
Follow the instructions up to the following command

sudo dpkg -i cuda-repo-ubuntu1804-11-7-local_11.7.1-515.65.01-1_amd64.deb

The above command will fail with the error message

The public CUDA GPG key does not appear to be installed.
To install the key, run this command:
sudo cp /var/cuda-repo-ubuntu1804-11-7-local/cuda-4783B890-keyring.gpg /usr/share/keyrings/

However running sudo cp /var/cuda-repo-ubuntu1804-11-7-local/cuda-4783B890-keyring.gpg /usr/share/keyrings/
does not fix the problem

Expected behavior
Installation should proceed successfully.

Additional context
@agthomas-ucsb I heard that you already installed CUDA onto nebula but I was getting this bug when trying to run the collab tutorials on nebula

I checked and it seems to be that Cuda 9.1 is on the machine, which is why I think I might need to update to Cuda 11.7

Kyle, did my work Wednesday resolve this issue?
