Thank you for taking the time to report this bug and helping to make Ubuntu better. The relevant dpkg terminal log says:
/usr/sbin/mkinitramfs: 156: /usr/sbin/mkinitramfs: Cannot fork /usr/sbin/update-initramfs: 180: /usr/sbin/update-initramfs: Cannot fork So the shell failed to fork subprocesses. This might be a bug in the shell or caused by a lack of free memory. According to Dmesg.txt this system has 2 GiB memory. So retry "sudo update-initramfs -u" after reboot. I am closing this bug. Please reopen in case you can reproduce the failure. Feel free to continue to report any other bugs you may find. ** Changed in: initramfs-tools (Ubuntu) Status: Confirmed => Invalid -- 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/1579332 Title: package linux-image-4.4.0-22-generic 4.4.0-22.39 failed to install/upgrade: run-parts: /etc/kernel/postinst.d/initramfs-tools exited with return code 2 Status in initramfs-tools package in Ubuntu: Invalid Bug description: apt-get update apt-get upgrade <---- No errors reported that I observed shutdown -r now <----- worked OK <error reporting dialog popped up> ProblemType: Package DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-22-generic 4.4.0-22.39 ProcVersionSignature: Ubuntu 4.4.0-22.39-generic 4.4.8 Uname: Linux 4.4.0-22-generic x86_64 ApportVersion: 2.20.1-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: bruce 1866 F.... pulseaudio Date: Sat May 7 16:34:19 2016 ErrorMessage: run-parts: /etc/kernel/postinst.d/initramfs-tools exited with return code 2 HibernationDevice: RESUME=UUID=3bcbcb26-5100-4193-a998-fdf1ad98cdec InstallationDate: Installed on 2016-05-03 (3 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) IwConfig: enp0s3 no wireless extensions. lo no wireless extensions.
