Thank you for taking the time to report this bug and helping to make Ubuntu better. The relevant dpkg terminal log says:
sed: kann /usr/share/plymouth/themes/ubuntu-gnome-text/ubuntu-gnome-text.plymouth nicht lesen: Datei oder Verzeichnis nicht gefunden E: /usr/share/initramfs-tools/hooks/plymouth failed with return 2. So reassigning to plymouth which ships /usr/share/initramfs- tools/hooks/plymouth. ** Package changed: initramfs-tools (Ubuntu) => plymouth (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/1549531 Title: package linux-image-extra-4.4.0-7-generic 4.4.0-7.22 failed to install/upgrade: run-parts: /etc/kernel/postinst.d/initramfs-tools exited with return code 2 Status in plymouth package in Ubuntu: Confirmed Bug description: Upgrade failure. But system is still running ... Edit (of 2016-02-25): Package in question is installed. So what's the issue? Is it just a wrong message I received from the system? (It was telling me that my system would be corrupted and probably unusable ... I'm happy it is not the case ...) Edit (of 2016-02-26): Because of some sound issues I applied following command to reinstall recent kernel: sudo apt-get install --reinstall linux-image-$(uname -r) That fixed my sound problems so far.
