Undetermined Error [IP: 149.20.20.22 80]
W: Конфликт распространения: http://deb.opera.com squeeze Release (ожидался squeeze, но получен stable)
W: Недоступен открытый ключ для следующих ID ключей:
1397BC53640DB551
Что я делаю не так?
В браузере адреса открываются.
P.S. Кстати точно такую же картину получаю на другой машине, где репозитории вообще дефолтные. Ничего внятного не нагугливается...
