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: nss (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to nss in Ubuntu. https://bugs.launchpad.net/bugs/1473453 Title: package libnss3 2:3.17.4-0ubuntu1 failed to install/upgrade: cannot copy extracted data for './usr/lib/x86_64-linux-gnu/nss/libnssckbi.so' to '/usr/lib/x86_64-linux-gnu/nss/libnssckbi.so.dpkg-new': unexpected end of file or stream Status in nss package in Ubuntu: Invalid Bug description: this error appeared after update ProblemType: Package DistroRelease: Ubuntu 15.04 Package: libnss3 2:3.17.4-0ubuntu1 ProcVersionSignature: Ubuntu 3.19.0-22.22-generic 3.19.8-ckt1 Uname: Linux 3.19.0-22-generic x86_64 ApportVersion: 2.17.2-0ubuntu1.1 Architecture: amd64 Date: Fri Jul 10 09:34:31 2015 DuplicateSignature: package:libnss3:2:3.17.4-0ubuntu1:cannot copy extracted data for './usr/lib/x86_64-linux-gnu/nss/libnssckbi.so' to '/usr/lib/x86_64-linux-gnu/nss/libnssckbi.so.dpkg-new': unexpected end of file or stream ErrorMessage: cannot copy extracted data for './usr/lib/x86_64-linux-gnu/nss/libnssckbi.so' to '/usr/lib/x86_64-linux-gnu/nss/libnssckbi.so.dpkg-new': unexpected end of file or stream InstallationDate: Installed on 2015-05-18 (52 days ago) InstallationMedia: Ubuntu-GNOME 15.04 "Vivid Vervet" - Release amd64 (20150422) RelatedPackageVersions: dpkg 1.17.25ubuntu1 apt 1.0.9.7ubuntu4 SourcePackage: nss Title: package libnss3 2:3.17.4-0ubuntu1 failed to install/upgrade: cannot copy extracted data for './usr/lib/x86_64-linux-gnu/nss/libnssckbi.so' to '/usr/lib/x86_64-linux-gnu/nss/libnssckbi.so.dpkg-new': unexpected end of file or stream UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nss/+bug/1473453/+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
