Невозможно открыть диспетчер обновлений или твик Ubuntu

Я не могу открыть Менеджер обновлений и Ubuntu Tweak

когда я открываю твик Ubuntu, я получаю этот журнал

user@laptop:~$ ubuntu-tweak

Это происходило после того, как я стер весь свой корень Ubuntu и использовал мой предыдущий существующий домашний раздел.

Существует значок уведомления об обновлении, который я не могу использовать, потому что ни один из параметров нельзя щелкнуть. Кроме того, этот значок не перестает отображаться даже после обновления из командной строки.
