+# Step 11 - Disable Unattended Upgrades
+
+## Overview
+
+Unattended upgrades can bring all sorts of uncertainty/troubles such as updates of NVIDIA drivers and have the potential to affects your Provider/K8s cluster. Impact of unattended upgrades can include:
+
+* `nvidia-smi` will hang on the host/pod
+* `nvdp plugin` will become stuck and hence K8s cluster will run in a non-desired state where closed deployments will be stuck in `Terminating` status
+
+## Disable Unattended Upgrades
+
+To disable unattended upgrades, execute these two commands on your Kubernetes worker & control plane nodes:\
+
+
+```
+echo -en 'APT::Periodic::Update-Package-Lists "0";\nAPT::Periodic::Unattended-Upgrade "0";\n' | tee /etc/apt/apt.conf.d/20auto-upgrades
+
+apt remove unattended-upgrades
+```
+
+## Verify
+
+These commands should output `0` following the disable of unattended upgrades.  Conduct these verifications  your Kubernetes worker & control plane nodes:
+
+```
+apt-config dump APT::Periodic::Unattended-Upgrade
+
+apt-config dump APT::Periodic::Update-Package-Lists
+```
+
+#### Example/Expected Output
+
+```
+# apt-config dump APT::Periodic::Unattended-Upgrade
+APT::Periodic::Unattended-Upgrade "0";
+
+# apt-config dump APT::Periodic::Update-Package-Lists
+APT::Periodic::Update-Package-Lists "0";
+```
