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: short-read ** Changed in: qt4-x11 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qt4-x11 in Ubuntu. https://bugs.launchpad.net/bugs/1472731 Title: package libqt4-declarative 4:4.8.1-0ubuntu4.8 failed to install/upgrade: short read on buffer copy for backend dpkg-deb during `./usr/lib/i386-linux-gnu/libQtDeclarative.so.4.8.1' Status in qt4-x11 package in Ubuntu: Invalid Bug description: Had a similar problem on same machine (Compaq Presario V2000) with Ubuntu 10.04...
