Thanks for taking your time to report this issue and help making Ubuntu better.
I've attached a corresponding bug report for Debian, latest version of the package has switched over to Python3. That has been synced and is currently in groovy-proposed. Looking at the patch (https://salsa.debian.org/debian/trash-cli/-/commit/e338213ce3e89a31407d3739c7fa6c0c39e7f404) this might be small and non-intrusive enough that a fix for 20.04 could be applied as a Stable Release Upgrade ( https://wiki.ubuntu.com/StableReleaseUpdates#Procedure)
