I am following [this guide](https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&Distribution=WSL-Ubuntu&target_version=2.0&target_type=deb_local) to install Cuda toolkit. I am installing in WSL2 using Ubuntu on x86-64 hardware. When I enter the command: ```auto $ sudo apt-get -y install cuda ``` I get the following errors: ```auto Err:7 http://security.ubuntu.com/ubuntu focal-updates/main amd64 libnss3 amd64 2:3.49.1-1ubuntu1.8 404 Not Found [IP: 91.189.91.39 80] Err:8 http://security.ubuntu.com/ubuntu focal-updates/main amd64 openjdk-11-jre-headless amd64 11.0.17+8-1ubuntu2~20.04 404 Not Found [IP: 91.189.91.39 80] Err:9 http://security.ubuntu.com/ubuntu focal-updates/main amd64 openjdk-11-jre amd64 11.0.17+8-1ubuntu2~20.04 404 Not Found [IP: 91.189.91.39 80] . . .

Have these files been moved/updated?
