4.Система-Параметры-Главное меню не запускается, клик ПКМ по меню с выбором пункта "Изменить меню" тоже.
5. При запуске Синаптика перестал запрашиваться пароль, равно как и при выполнении операций в терминале требующих повышенных привилегий (sudo).

Кто-нибудь знает, как исправить перечисленные проблемы? В поиске ничего путного не нашёл.

sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade

[AsAn]

cortes_, не помогло.

команда apt-get upgrade вообще ничего не обновила. Только вывела список пакетов, которые останутся в неизменном виде и завершила работу.
