If you are hit by this issue, it seems sufficient to simply ask dpkg to finish configuration as it seems the prerm script isn't retried
$ dpkg --configure -a Or you can just re-run your upgrade command (e.g. "apt upgrade") which should do the same plus finish any upgrades that didn't finish (which may be the case) - you'll probably want to do that either way. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to avahi in Ubuntu. https://bugs.launchpad.net/bugs/1760128 Title: package avahi-dnsconfd 0.6.32~rc+dfsg-1ubuntu2 failed to install/upgrade: subprocess new pre-removal script returned error exit status 1 Status in avahi package in Ubuntu: Triaged Bug description: Ubuntu Update 30.03.18 ProblemType: Package DistroRelease: Ubuntu 16.04 Package: avahi-dnsconfd 0.6.32~rc+dfsg-1ubuntu2 ProcVersionSignature: Ubuntu 4.4.0-116.140-generic 4.4.98 Uname: Linux 4.4.0-116-generic x86_64 NonfreeKernelModules: nvidia_uvm nvidia ApportVersion: 2.20.1-0ubuntu2.15 Architecture: amd64 Date: Fri Mar 30 16:32:50 2018 ErrorMessage: subprocess new pre-removal script returned error exit status 1 InstallationDate: Installed on 2016-01-31 (788 days ago) InstallationMedia: Ubuntu-MATE 16.04 LTS "Xenial Xerus" - Alpha amd64 (20160131) RelatedPackageVersions: dpkg 1.18.4ubuntu1.4 apt 1.2.26 SourcePackage: avahi Title: package avahi-dnsconfd 0.6.32~rc+dfsg-1ubuntu2 failed to install/upgrade: subprocess new pre-removal script returned error exit status 1 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/1760128/+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
