Kaleb [1] filed a deletion request for python-pymctranslate [2]: The original project has related low demand for linux users, and this package has been abandoned. There is also a problem involving UI flickering for Linux/MacOS users, and it doesn't seem to be getting fixed anytime soon, since is a small team of developers.
