Comment 3 for bug 307735

Further analysed :

=> Basically the script check the answers you gave about your keyboard, etc... and tries to set them up...And It looks like thehe doesn't like so much the keyboard type you select (or the one which is selected automatically) !

Anyways, one of the choice you make is making console-cyrillic crazy :-)

Try to issue as root :
dpkg-reconfigure console-cyrillic
And If you can figure _which_ choice , this would be easier after that to find a work around or narrowing the bug or misconfiguration you hit !

To sum up, at least one of this choice is not good :
console-cyrillic/ttys
console-cyrillic/fontstyle
console-cyrillic/fontsize
console-cyrillic/kbdtype
console-cyrillic/toggle
console-cyrillic/switch
console-cyrillic/encoding
console-cyrillic/bootsetup
console-cyrillic/change_config

I put this bug as needing more info and incomplete.
