Hi, Upstream migrated to Python 3 in version 19.7.9, so it can be uploaded to fix this.
Note: version 19.7.15 depends on development version of python-caja (1.23), so it's too new for now (until MATE 1.24 is released in the beginning of 2020). Changelog: https://bazaar.launchpad.net/~robert-tari/cajarename/trunk/view/head:/debian/changelog
