Thank you for taking the time to report this bug and helping to make Ubuntu better. The relevant dpkg terminal log says:
cp: omitting directory '/etc/udev/rules.d/70-persistent-net.rules' E: /usr/share/initramfs-tools/hooks/udev failed with return 1. The udev hook comes from the udev package. So re-assigning to the systemd source package. ** Package changed: initramfs-tools (Ubuntu) => systemd (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1651883 Title: package linux-firmware 1.157.6 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 Status in systemd package in Ubuntu: Confirmed Bug description: during a do-release-upgrade from 14.04 ProblemType: Package DistroRelease: Ubuntu 16.04 Package: linux-firmware 1.157.6 ProcVersionSignature: Ubuntu 4.2.0-30.36~14.04.1-generic 4.2.8-ckt3 Uname: Linux 4.2.0-30-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.4 Architecture: amd64 Date: Wed Dec 21 13:31:06 2016 Dependencies: ErrorMessage: subprocess installed post-installation script returned error exit status 1 PackageArchitecture: all RelatedPackageVersions: dpkg 1.18.4ubuntu1.1 apt 1.2.15ubuntu0.2 SourcePackage: initramfs-tools Title: package linux-firmware 1.157.6 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 UpgradeStatus: Upgraded to xenial on 2016-12-21 (0 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1651883/+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
