[fix] : update cache before running install

[rahulait]

Fixes NVIDIA/gpu-operator#1244

Root cause

Package versions are rotated/updated on mirrors over time. The _install_driver() function in the nvidia-driver script was calling apt-get install without first running apt-get update. This meant it was using stale package lists that referenced package versions (like python3.10_3.10.12-1~22.04.7) that had been rotated out of the Ubuntu repositories in favor of newer/patched versions. This resulted in 404 errors when fetching those stale packages and install script exited with error.

Fix

The fix proposes running apt-get update before running any apt install.

Pull request overview

This PR fixes a package installation failure caused by stale package cache by ensuring apt-get update runs before driver installation. The fix adds error handling to the cache update operation and calls it at the appropriate point in the init sequence.

Changes:

• Added error handling to _update_package_cache() to catch and report update failures
• Called _update_package_cache() before _install_driver() in the init() function
• Applied changes consistently across Ubuntu 22.04 and 24.04 driver scripts (both standard and precompiled variants)

Thanks @rahulait. I assume this was only affecting the precompiled Ubuntu containers since I see you only added a call to update_package_cache there?

Yeah, others already have the call to update_package_cache in them
