Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that there was an error on your system when trying to install a particular package. Please execute the following command, as it will clear your package cache, in a terminal:
sudo apt-get clean Then try performing the update again. This will likely resolve your issue, but the failure could be caused by filesystem or memory corruption. So please also run a fsck on your filesystem(s) and a memory test. Thanks in advance! [This is an automated message. I apologize if it reached you inappropriately; please just reply to this message indicating so.] ** Tags added: corrupted-package ** Changed in: linux-lts-utopic (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-lts-utopic in Ubuntu. https://bugs.launchpad.net/bugs/1431510 Title: package linux-image-3.16.0-31-generic 3.16.0-31.41~14.04.1 failed to install/upgrade: cannot copy extracted data for './lib/modules/3.16.0-31-generic/kernel/net/sched/sch_netem.ko' to '/lib/modules/3.16.0-31-generic/kernel/net/sched/sch_netem.ko.dpkg- new': unexpected end of file or stream Status in linux-lts-utopic package in Ubuntu: Invalid Bug description: This problem always occurs while installing updates.
