-обновление-версии останавливается

Я посреди a do-release-upgrade 10.04 к 12,04 серверам, но это, кажется, остановилось при обновлении mysql

Configuration file `/etc/mysql/my.cnf'
 ==> Modified (by you or by a script) since installation.
 ==> Package distributor has shipped an updated version.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.
*** my.cnf (Y/I/N/O/D/Z) [default=N] ? n

Журналы в /var/log/dist-upgrade не покажите никакой другой признак ошибок.

Кто-либо может рекомендовать лучше всего следующий шаг?
