We apply the Dual Ramsey Theorem of Graham and Rothschild to prove the Ramseyproperty for classes of finite Boolean algebras with distinguished ideals. Thisallows us to compute the universal minimal flow of the group of automorphismsof $\mathcal{P}(\omega_1)/\rm{fin},$ should it be isomorphic to$\mathcal{P}(\omega)/\rm{fin}$ or not, and of other quotients of power setalgebras. Taking Fra\"iss\'e limits of these classes, we can compute universalminimal flows of groups of homeomorphisms of the Cantor set fixing some closedsubsets.
