Всем привет, использую Ubuntu Linux с версии 12.04 и мне эта система очень нравится. Сейчас у меня установлена 18.04 и я хочу обновиться на 19 версию. Однако, каждый раз при попытке накатить апдейты, вылазит ошибка:
Failed to download repository information
Я использую такую команду для обновления:
update-manager -d
После выполнение этой команды, в терминале - ругня:
/usr/bin/update-manager:28: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.
from gi.repository import Gtk
/usr/lib/python3/dist-packages/UpdateManager/UnitySupport.py:29: PyGIWarning: Dbusmenu was imported without specifying a version first. Use gi.require_version('Dbusmenu', '0.4') before import to ensure that the right version gets loaded.
from gi.repository import Dbusmenu, Unity
/usr/lib/python3/dist-packages/UpdateManager/UnitySupport.py:29: PyGIWarning: Unity was imported without specifying a version first. Use gi.require_version('Unity', '7.0') before import to ensure that the right version gets loaded.
from gi.repository import Dbusmenu, Unity
Если я выполняю sudo apt update, то вижу другое:

Кто может подсказать что я делаю не так? Как обновиться на 19-ю версию Ubuntu?
