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 Bugs, which is subscribed to 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1740299/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
