Hi Dzintars, dnsmasq user is set up by the preinst of dnsmasq right before the chown. But nogroup is a generic group not tied to dnsmasq that should always exists.
You should have such a group as well and therefore the error should (tm) not exists :-) What does the following give you: $ getent group nogroup I get a high group id like: nogroup:x:65534: It is part of base-passwd and set up to exist on the inital install. I could only think of a system that had someone hard remove that group to trigger this error. Maybe checking for the id as suggested above help you to start sorting it out. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1740299 Title: package dnsmasq-base 2.78-1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 Status in dnsmasq package in Ubuntu: Incomplete Bug description: Just got this error after upgrade ProblemType: Package DistroRelease: Ubuntu 17.10 Package: dnsmasq-base 2.78-1 ProcVersionSignature: Ubuntu 4.13.0-21.24-generic 4.13.13 Uname: Linux 4.13.0-21-generic i686 ApportVersion: 2.20.7-0ubuntu3.6 Architecture: i386 Date: Tue Dec 26 23:33:28 2017 DuplicateSignature: package:dnsmasq-base:2.78-1 Setting up dnsmasq-base (2.78-1) ... chown: invalid group: ‘dnsmasq:nogroup’ dpkg: error processing package dnsmasq-base (--configure): subprocess installed post-installation script returned error exit status 1 ErrorMessage: subprocess installed post-installation script returned error exit status 1 Python3Details: /usr/bin/python3.6, Python 3.6.3, python3-minimal, 3.6.3-0ubuntu2 PythonDetails: /usr/bin/python2.7, Python 2.7.14, python-minimal, 2.7.14-2ubuntu1 RelatedPackageVersions: dpkg 1.18.24ubuntu1 apt 1.5.1 SourcePackage: dnsmasq Title: package dnsmasq-base 2.78-1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 UpgradeStatus: Upgraded to artful on 2017-12-27 (0 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1740299/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
