@tonyr so this solved it for you?
sudo systemctl stop systemd-udevd systemd-udevd-kernel.socket systemd-udevd-control.socket
Just wanted to confirm what fixed your issue. And this is for a machine w/o an NVIDIA gpu, correct?
I think we have a CPU-only Lambda Stack you can install with:
LAMBDA_REPO=$(mktemp) && \
wget -O${LAMBDA_REPO} https://lambdalabs.com/static/misc/lambda-stack-repo.deb && \
sudo dpkg -i ${LAMBDA_REPO} && rm -f ${LAMBDA_REPO} && \
sudo apt-get update && sudo apt-get install -y lambda-stack
