On just one of my three Wheezy machines, I often get bad downloads when I run apt-get upgrade. This started abruptly seven weeks ago. The general form of the apt-get error includes this:
dpkg: error processing /var/cache/apt/archives/[package].deb (--unpack): short read on buffer copy for backend dpkg-deb during [package] Then I find that dd can't read all of the cached deb file. In one case, "ls -l" said the file was 5.8 MB, but dd </var/cache/apt/archives/[package].deb >/dev/null dd: reading `standard input': Input/output error ... 2854912 bytes (2.9 MB) copied, 22.261 s, 128 kB/s If I remove the bad deb file and call apt-get to reinstall that package, everything runs to completion. So I have been able to keep the system updated. I thought the unreadable file might indicate one or more bad blocks on the disk. A recent boot ran fsck (as it does every 25 boots), and no filesystem errors were found. What might be giving rise to these truncated deb-file downloads? How might I fix the problem?
