ubuntu@ubuntu:~$ uname -a Linux ubuntu 3.2.0-88-virtual #126-Ubuntu SMP Mon Jul 6 21:50:59 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Installed ntp: % sudo apt-get install ntp ... http://archive.ubuntu.com/ubuntu/ precise-updates/main ntp amd64 1:4.2.6.p3+dfsg-1ubuntu3.4 ubuntu@ubuntu:~$ grep ntp /etc/group ntp:x:112: Then do-release-upgrade to move to 14.04 with no issues. Examining the postinst scripts in current precise ( ), and various trusty versions of the ntp package, the script is always idempotent w.r.t adding the ntp group. It's not clear to me which version of the ntp package had a post-inst script that wasn't idempotent. Getting a copy of the ntp.postinst script that is failing would be most useful. One workaround to the dist-upgrade issue is to apt-get remove --purge ntp (which will run the postrm hook to remove the ntp group) prior to upgrading. ** Changed in: ntp (Ubuntu) Status: New => Incomplete ** Changed in: ntp (Ubuntu) Assignee: Ryan Harper (raharper) => (unassigned) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/1372051 Title: ntp postinst user/group add commands are not idempotent Status in ntp package in Ubuntu: Incomplete Bug description: At do release upgrade from 12.04.05 to 14.04.01, the ntp package failed: Errors were encountered while processing: ntp Error in function: A fatal error occurred Please report this as a bug and include the files /var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in your report.
