Hi,
packages have a set of defined usernames that are collision free among each
other but as you encountered might collide with other things - especially if a
username is rather short.
Commonly package names (ntp, mysql, ceph, ...) or package name plus suffix
(libvirt-*, ...), are users used by the system.
While I agree that there could be added some code to support that, it is most
likely error prone and unlikely to happen (quite some effort for very low
gain).
That is especially true for ntp which is (in later releases) no more in main
and a change like that would not be SRUable to older releases.
I'll set this to won't fix as I want to avoid people expecting this to
happen.

Title:
Install fails when 'ntp' user already exists
Status in ntp package in Ubuntu:
Won't Fix
Status in ntp source package in Trusty:
Confirmed
Bug description:
I work in an enterprise environment where usernames are decided
centrally. A user has been given the user name 'ntp'. I need to be
able to tell the ntp package to use a different username, but the
install script assumes that the ntp:ntp user/group is available and
valid.
At a minimum, this code needs to accept a configured username variable
instead of hard-coding ntp.
if [ "$1" = "configure" ]; then
addgroup --system --quiet ntp
adduser --system --quiet --ingroup ntp --no-create-home ntp
chown -R ntp:ntp /var/lib/ntp /var/log/ntpstats
fi
