package ntp 1:4.2.8p10+dfsg-5ubuntu7.1 failed to install/upgrade: installed ntp package post-installation script subprocess returned error exit status 1

I also had the bug on grub-efi-amd64-signed
 https://bugs.launchpad.net/ubuntu/+source/grub2-signed/+bug/1753518

Perhaps there is a link between both.

Hi,
the grub bug certainly is a different bug.

Here from your log:
Paramétrage de ntp (1:4.2.8p10+dfsg-5ubuntu7.1) ...
 Le groupe « ntp » existe déjà, sans être un groupe système. Fin de la procédure.

That means your system has a colliding user named "ntp" which blocks the packages installation.
The only solution I see is rename the current ntp user [1] then ntp installation would work.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete.

If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Or if you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.
