Does locking affect running processes?

Question

I would like to run the updates available to my Ubuntu device with the built-in Software Updater application, but I would like to lock my system for the time of the update for security reasons. (Others can physically access my computer.)

I would like to know if that was possible? I am also interested in any solution using terminal, but I need to make sure that my user is locked during the update.

edit My question is not a duplicate, since the real question here is to know whether locking the screen still allows processes started by my user to run, or not. I lock my system on daily basis, have no problems with that. Please confirm if locking doesn't affect the execution of the updater application.

Locking the system does not affect running processes if they expect any interaction.

In the special case of a system update, queries may be limited, but not be totally excluded.

E.G.:

sudo apt-get --assume-yes update
