При установке Ubuntu под Xen часто возникает ошибка:

Mar 24 15:55:13 db console-kit-daemon[13251]: WARNING: Error waiting for native console 58 activation: Invalid argument
Mar 24 15:55:13 db console-kit-daemon[13251]: WARNING: Error waiting for native console 8 activation: Invalid argument
Mar 24 15:55:13 db console-kit-daemon[13251]: WARNING: Error waiting for native console 43 activation: Invalid argument

Mar 24 15:55:13 db console-kit-daemon[13251]: WARNING: Error waiting for native console 12 activation: Invalid argument

лечится это так:

rm /etc/dbus-1/system.d/ConsoleKit.conf
rm /usr/share/dbus-1/system-services/org.freedesktop.ConsoleKit.service
invoke-rc.d dbus restart

Незнаю, правильно это или нет, но, демон уже не запускается при старте

‘Account has expired’ message when adding a new user, after “passwd -l root”

This seems to be related to the use of “passwd -l root”.
Until the Debian fix shows up in hardy, here is a workaround, thanks to Nicolas François:

 sudo passwd --unlock root
 sudo usermod --lock root
