[Koha] Problem with install Koha packages on ubuntu server 12.04 amd64

[Uy nguyễn quốc]

I'm doing exactly as in this tutorial: http://wiki.koha-community.org/wiki/Koha_on_ubuntu_-_packages.
When i install on ubuntu desktop 12.04 x64 a month ago, it all works totally. It was Koha 3.8.6
Now i'm trying install on ubuntu server 12.04 amd64, when i type:

 $sudo apt-get install koha-common, i got message:"
The following packages have unmet dependencies:
Koha-common: Depends: libchi-driver-memcached-perl but it is not going to install
Koha-common: Depends: libchi-perl but it is not going to install
E: Unable to correct problems, you have held broken packages "

Any one can help? I try to find some way to fix unmet dependencies on Ubuntu forum, but no help. System upgrade totally.
