webmin instalation problem on sarge

[Vadik <vadik@kutsyy.com>]

I am running /sarge and I am trying to install webmin 1.150-1, but 
installation breaks.  Here is output:

---------------------------------
xxx:/etc/logrotate.d# apt-get install webmin

xxx:/etc/logrotate.d# ls /etc/webmin

Any recommendation of what can be wrong?  My understanding that this 
error has something to do with openssh.

Thanks,
