Just add libopts25 along with ntp like this sudo apt-get install ntp libopts25:

$ sudo apt-get install ntp

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
ntp : Depends: libopts25 (>= 1:5.18.7) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

$ sudo apt-get install ntp libopts25

You can install ntp server using following commands:

If you are using ubuntu server use sudo apt-get install ntp.

If you are using centos or RHEL then use sudo yum install ntp.

If this does not work try updating the source list repo.
