Thank you for taking the time to report this bug and helping to make Ubuntu better. The relevant dpkg terminal log says:
E: No boot partition found ! The df log shows that no /boot partition is mounted. Can you check if you have a separate boot partition and mount it? ** Changed in: initramfs-tools (Ubuntu) Status: Confirmed => Incomplete -- 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/1576762 Title: package initramfs-tools 0.122ubuntu8 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 Status in initramfs-tools package in Ubuntu: Incomplete Bug description: just updating ubuntu mate, then this erroe occured ProblemType: Package DistroRelease: Ubuntu 16.04 Package: initramfs-tools 0.122ubuntu8 Uname: Linux 3.4.108 armv7l ApportVersion: 2.19.1-0ubuntu5 Architecture: armhf Date: Fri Apr 29 17:14:59 2016 DuplicateSignature: package:initramfs-tools:0.122ubuntu8:subprocess installed post-installation script returned error exit status 1 ErrorMessage: subprocess installed post-installation script returned error exit status 1 PackageArchitecture: all RelatedPackageVersions: dpkg 1.18.4ubuntu1 apt 1.2.10ubuntu1 SourcePackage: initramfs-tools Title: package initramfs-tools 0.122ubuntu8 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 UpgradeStatus: Upgraded to xenial on 2016-04-29 (0 days ago) mtime.conffile..etc.initramfs.tools.initramfs.conf: 2016-02-21T22:22:01 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1576762/+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
