Release upgrade fails

[Roman Zabaluev]

Hello, there's bug appeared and the upgrade failed during 'do-release-upgrade'. By the way, when I do release upgrade it always fails, like when I was updating to 14.04 from 12.04 it failed like this.

And that's happened when I entered 'y' to confirm deletion of 'unused' packages.
By the way, why this list includes a lot of needed packages marked as 'for removal' like a lot of php packages, aptitude-common?

/var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log should be linked as attachments.

Exception:

Пожалуйста, сообщите об этой ошибке и включите файлы
/var/log/dist-upgrade/main.log и /var/log/dist-upgrade/apt.log в ваш
отчёт. Обновление было отменено.
Ваш оригинальный файл sources.list был сохранён в
/etc/apt/sources.list.distUpgrade.
