Replacing lost drivers?

[Moltke]

The autoremove -F command must have wiped the drivers. They had been working fine.

For the sake of learning and avoiding this kind of things to happen, would you mind telling which broken packages were you dealing with, if possible, please? Since your thread called my attention I ran into googling "recover lost drivers ubuntu" and "drivers directory location in Ubuntu" For the "recover lost drivers" most of the proposed solutions were reinstalling, others suggested booting into a live cd and trying to download drivers from there. Drivers are located in /lib/modules and /sys/modules/ so I guess that whatever procedure you were performing somehow broke/deleted those. I can only think of two possible ways for recovering lost drivers or any other important files/configurations:
1. -Create a system restore point with systemback, so in theory one could be able of restoring the system to a state where drivers are still present.

2. - Use some app like aptik to backup any important files like drivers and configurations. The advantage of aptik is that one can save to an external storage like a flash drive or a usb hdd, so in case systemback way doesn't work there's a plan B.

I actually think of a third solution, but I'm not sure whether it'd work or not; I think open a terminal and running

Code:

$ sudo apt-get update && sudo apt-get upgrade

would do the trick, but I'm really not sure and have not intention to try this 8)
