I needed to downgrade my Nvidia drivers because my older GPU wasn’t behaving well with the newest versions. However, apt always wanted to upgrade them again. To prevent this, we can lock certain packages:
sudo apt-mark hold $(dpkg -l | grep nvidia | grep ^ii | awk '{print $2}')To unlock again in future:
sudo apt-mark unhold $(dpkg -l | grep nvidia | grep ^hi | awk '{print $2}')
