как решить «Нет модуля с именем 'distro_info'» на обновление

Я пытаюсь обновить свой ubuntu 18.04, но когда я пытаюсь запустить sudo do-release-upgrade , я получаю следующую ошибку:

Checking for a new Ubuntu release
Get:1 Upgrade tool signature [1.554 B]

Original exception was:

    import distro_info
ModuleNotFoundError: No module named 'distro_info'

Я попытался установить python3-distro-info (который уже был установлен и обновлен) и python-distro-info, которые я установил, но ничего не изменил.
Что я могу сделать для успешного обновления?
