Learning Curve

Learning Curve is a quest in Fallout 4. It is a Radiant quest chain with multiple locations being targeted.

Quick walkthrough

 * 1) Accept a patrol from Quinlan
 * 2) Go to the airport to get the Scribe companion
 * 3) Go to the target area and bring the Scribe to the marked terminal
 * 4) Return to Quinlan

Boston mayoral shelter
The shelter is west of Fort Hagen, there's a terminal in the raised office outside that can unlock the door. Once inside there's a laser turret behind the security gate and two more near the terminal.

Bugs
The Scribe may not interact with the terminal when you bring them to it. IF that happens reverting to a previous save BEFORE entering the shelter should fix it, alternately leaving, waiting 3-4 days and returning may fix it as well.

One way to fix the bug is to bring up the console, target the scribe and type in "disable" and then "enable".
