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: failed-to-read ** Changed in: apport (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to apport in Ubuntu. https://bugs.launchpad.net/bugs/1166332 Title: package apport 2.0.1-0ubuntu14 failed to install/upgrade: failed to read on buffer copy for md5hash: Input/output error Status in “apport” package in Ubuntu: Invalid Bug description: installation or removal of software package failed ProblemType: Package DistroRelease: Ubuntu 12.04 Package: apport 2.0.1-0ubuntu14 ProcVersionSignature: Ubuntu 3.2.0-39.62-generic 3.2.39 Uname: Linux 3.2.0-39-generic x86_64 NonfreeKernelModules: nvidia ApportLog: ApportVersion: 2.0.1-0ubuntu14 AptOrdering: apport: Configure apport-gtk: Configure Architecture: amd64 CrashReports: 600:0:125:123920:2013-04-08 12:59:55.027258000 -0400:2013-04-08 13:13:20.643258738 -0400:/var/crash/apport.0.crash Date: Mon Apr 8 12:59:54 2013 ErrorMessage: failed to read on buffer copy for md5hash: Input/output error InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) MarkForUpload: True PackageArchitecture: all SourcePackage: apport Title: package apport 2.0.1-0ubuntu14 failed to install/upgrade: failed to read on buffer copy for md5hash: Input/output error UpgradeStatus: Upgraded to precise on 2012-08-14 (237 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1166332/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
