To do so, run the below command to edit the file /etc/apt/apt.conf.d/20auto-upgrades: ``` sudo vi /etc/apt/apt.conf.d/20auto-upgrades ``` Then comment out all the lines you see there, and edit the file as: ``` APT::Periodic::Update-Package-Lists "0"; APT::Periodic::Download-Upgradeable-Packages "0"; APT::Periodic::AutocleanInterval "0"; APT::Periodic::Unattended-Upgrade "0"; ``` Then save and quit, it should disable all the update in the OS now, and for the security safety, you need to do the manually upgrade afterward with: ``` apt-get update && apt-get upgrade ``` And everytime after the update, it may crash the Cuda again, so you better check it buy running the command below and see if it runs correctly without errors: ``` nvidia-smi ``` ### Remove Nvidia stuff from Auto-update Or, you may want the unattanded update be active to apply all the security patch, just not those Nvidia stuff. To do so, run the below command to edit the file /etc/apt/apt.conf.d/50unattended-upgrades, there should be some lines called "Unattended-Upgrade::Package-Blacklist", editing the lines to look like this and save: ``` Unattended-Upgrade::Package-Blacklist { "nvidia-"; "libnvidia-"; "cuda"; } ``` You may also need to consider adding additional lines if you see any other NVIDIA driver names in the output of the command: ``` apt list --installed | grep nv ``` ### Prevent update Nvidia stuff from apt update Although it is not nessuary, because update all the server packages means you always needs to overlook all the package being update and test, instead of Nvidia stuff only. Some poeple may just want it for specific purpose. To do so, all you need to use is: apt-mark For example, if you need to onhold cuda from its update, you may enter the command: ``` apt-mark hold cuda ``` And release it with: ``` apt-mark unhold cuda ``` This should much easier to editing APT Preferences File instead for the same purpose. apt-mark support fnmatch() and regex format for the package name as well.
