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: libav (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libav in Ubuntu. https://bugs.launchpad.net/bugs/1463860 Title: package libavformat56 (not installed) failed to install/upgrade: cannot copy extracted data for './usr/lib/i386-linux- gnu/libavformat.so.56.1.0' to '/usr/lib/i386-linux- gnu/libavformat.so.56.1.0.dpkg-new': unexpected end of file or stream Status in libav package in Ubuntu: Invalid Bug description: crash after installation of new software ProblemType: Package DistroRelease: Ubuntu 15.04 Package: libavformat56 (not installed) ProcVersionSignature: Ubuntu 3.19.0-15.15-generic 3.19.3 Uname: Linux 3.19.0-15-generic i686 ApportVersion: 2.17.2-0ubuntu1 Architecture: i386 Date: Wed Jun 10 18:21:33 2015 DuplicateSignature: package:libavformat56:(not installed):cannot copy extracted data for './usr/lib/i386-linux-gnu/libavformat.so.56.1.0' to '/usr/lib/i386-linux-gnu/libavformat.so.56.1.0.dpkg-new': unexpected end of file or stream ErrorMessage: cannot copy extracted data for './usr/lib/i386-linux-gnu/libavformat.so.56.1.0' to '/usr/lib/i386-linux-gnu/libavformat.so.56.1.0.dpkg-new': unexpected end of file or stream InstallationDate: Installed on 2015-05-29 (12 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Release i386 (20150422) RelatedPackageVersions: dpkg 1.17.25ubuntu1 apt 1.0.9.7ubuntu4 SourcePackage: libav Title: package libavformat56 (not installed) failed to install/upgrade: cannot copy extracted data for './usr/lib/i386-linux-gnu/libavformat.so.56.1.0' to '/usr/lib/i386-linux-gnu/libavformat.so.56.1.0.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/libav/+bug/1463860/+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
