No action; perform a simulation of events that would occur based on the current system state but do not actually change the system. Locking will be disabled (Debug::NoLocking) so the system state could change while apt-get is running. Simulations can also be executed by non-root users which might not have read access to all apt configuration distorting the simulation. A notice expressing this warning is also shown by default for non-root users (APT::Get::Show-User-Simulation-Note). Configuration Item: APT::Get::Simulate.
