[Bug 1661185] Re: /sbin/dhclient-script causes insufficient feedback "/sbin/dhclient-script: 28: .: Can't open /usr/share/sendmail/dynamic"

[Simon Quigley]

Marking as Invalid because the release is EOL is not correct. Marking as Incomplete. Also, 18.04 is (at the time of writing) still in development, and you should expect some breakage.

Reporter, is this still present on 17.10 or 16.04?

** Changed in: isc-dhcp (Ubuntu)

Title:
  /sbin/dhclient-script causes insufficient feedback "/sbin/dhclient-
  script: 28: .: Can't open /usr/share/sendmail/dynamic"

Status in isc-dhcp package in Ubuntu:
  Incomplete

Bug description:
  Since `/sbin/dhclient-script` is a bash script it's very hard to trace
  back the error/figure out what actually happened because `bash` can't
  provide information about exceptional states (line 28 is just the
  error logging function).

  I'd be appreciated if the script was ported to Python because it
  provides state-of-the-art scripting facilities.

  I encounter this situation during `sudo systemctl restart
  networking.service`.
