Just want to clarify.
System LambdaBlade with Ubuntu 20.04:
Is there a difference between the command here Getting-started Removing and Installing Lambda-stack-in-ubuntu
[Uninstall (purge) the existing Lambda Stack by running:

sudo rm -f /etc/apt/sources.list.d/{graphics,nvidia,cuda}* && \
dpkg -l | \
awk '/cuda|lib(accinj64|cu(blas|dart|dnn|fft|inj|pti|rand|solver|sparse)|magma|nccl|npp|nv[^p])|nv(idia|ml)|tensor(flow|board)|torch/ { print $2 }' | \
sudo xargs -or apt -y remove --purge

Then, install the latest Lambda Stack by running:

wget -nv -O- https://lambdalabs.com/install-lambda-stack.sh | sh -

]
and
sudo apt-get remove lambda-stack-cuda && sudo apt-get install lambda-stack-cuda
