Yes they absolutely did. There were quite a few surprises. The resistance of the Ukrainian people, especially the leadership. The effectiveness of small shoulder mounted weapons in taking out armoured vehicles. The incredibly poor logistical capability of the Russian forces who thought they could just drive into Kiev without infantry support, or even bringing enough fuel.

The way the Russian forces conducted themselves initially has led to the belief that they believed they'd have local support. Purge of their security people supports this idea too. Putin thought he'd paid for insurgency in Ukraine and instead had some uncommonly wealthy spies.
