Here is a good article that helps explain the Russian strategic strategy thus far. In short, the FSB conducted a survey in Ukraine in February:
Trust in the office of the president sat at 27%, with 67% distrustful of the presidency. President Volodymyr Zelenskiy had poor approval ratings at −34, but a high proportion of Ukrainians polled still professed that they would vote for him over other candidates. The Ukrainian Army, both regular and reserve, was highly trusted, with 68% of the population supportive, as were military veterans, while regional and municipal governments were comparatively well-trusted with over 40% of the population having a favourable opinion of them.
However, other institutions enjoyed approval figures that ranged from mediocre to poor, including the police at 28% and domestic security services at 23%. Trust in the Rada – the Ukrainian parliament – and in political parties was abysmal, at 11% and 8% respectively. And when it came to willingness to serve in the military or otherwise resist a foreign invasion, 40% of respondents stated that they would not defend Ukraine.
