I don't think so, but people have different perspectives on this.

My understanding is that the conflict is over provinces adjacent to Russia. That's primarily for access to the Russian naval base in Crimea, but it's also about who controls the ethnically Russian provinces.

Some expect that Russia is trying to conquer the entirety of Ukraine and then continue on into other parts of eastern Europe. I don't think that's right, but I'll acknowledge that if it were, Putin's not going to just announce that to the world.
