Hopefully I can help some folks with this. I had this issue with my '25 Nautilus - it failed every day for a few weeks including when I initiated it manually. It would often go into low battery mode which I suspected was related to the update attempt. My hypothesis is that it was draining battery to a point where the car intervened and stopped the update.
Sidebar for context: I use HomeAssistant (an open source home automation platform) which has an unofficial plugin for the Ford/Lincoln app - it uses the same API as the app, but exposes some pretty nice features like the 12V battery level. Because I have a very short daily commute, my 12V battery doesn't get a lot of time to charge. It seems to hover between 50 and 65% full. I have the hybrid and I've come to realize this car likely wasn't designed for a super short daily commute without a ton of other travel...but I digress.
Back to the main story: I went for a longer drive, about 4 hours total, and observed the battery was above 80%. Sure enough, it succeeded when I ran the update! It only went down about 14% and it goes into low battery mode at about 40%, so I'm still not sure why it seems to need such a high battery, but at least in my case that did it. Maybe others who often drive very short drives can confirm my findings if they take a longer trip, ensuring the 12V battery is relatively charged, and then attempt the update again.
