Even if you disagree with my assessment of Russia’s annexation, isn’t an international body ( that Russia itself has membership) working with your people, with guarantees for self rule and an end to the war better than status quo?
If you’ve supported Donbas independence, with wishes for greater ties to Russia instead of Europe, you still get that in this agreement. Donbas can still legitimately join Russia in a few decades, and still trade with them now.
Linux Mint and PopOS are usually listed as friendly distros and are derivatives of Ubuntu without Ubuntu controversies like Snap. Mint even has an alternative direct Debian base skipping some Ubuntu packages, so might be ironically closer to old Ubuntu in that flavor.
If you’re open to going non-debian, Manjaro is often sold as the more user friendly Arch. (Edit - a recent Manjaro controversy has people recommending EndeavorOS instead for an Arch wrapper. I’ve not tried that one myself).
Debian or Arch aren’t bad to use directly either and are far more newbie friendly than they were a decade ago even if not as out of the box opinionated as their derivatives.
