[Bug 1662006] Re: package samba 2:4.4.5+dfsg-2ubuntu5.2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Hi,
thank you for your report.
>From what I read it seems that your samba is installed/configured in a way that the service won't start. Since the services are tried to be restarted on every update to pick up the changes it will fail that restart every time it updates and notifies you of an issue.

>From your log:

I wonder about the last message thou - have you an ipv6 only setup or anything like it?
Otherwise as outlined before maybe just the config of smbd/nmbd is in a bad state.

I've seen several reports like this, but since it is not reproducing
from the default install it usually is related to some sort of custom
config. Unfortunately that was often done months or even years ago.

Title:
  package samba 2:4.4.5+dfsg-2ubuntu5.2 failed to install/upgrade:
  subprocess installed post-installation script returned error exit
  status 1

Status in samba package in Ubuntu:
  Incomplete

Bug description:
  I was not aware of any bug.  However I have received a message every time I have run Ubuntu over the last 2 or 3 days (perhaps 10 -12 times) saying that a system error had occured and inviting me to report it.  On this and only this occasion has the error been followed by questions and this web page opening in my browser. As questions were centred around Samba and Windows network it could coincide with a wifi enabled Epson printer that my son has installed and, apparently connected to our home network.  I have not made any attempt to connect to the network but I did notice on 3rd February that the printer appeared in network settings. I don't know if this is of any help.
  Regards, Brian
