you have held broken packages

[Dolph Mathews]

This bit appears to occur in successful runs:

    W: Failed to fetch bzip2:/var/lib/apt/lists/partial/az3.clouds.archive.ubuntu.com_ubuntu_dists_precise-updates_main_binary-amd64_Packages Hash Sum mismatch

    W: Failed to fetch bzip2:/var/lib/apt/lists/partial/az3.clouds.archive.ubuntu.com_ubuntu_dists_precise-updates_main_binary-i386_Packages Hash Sum mismatch

    E: Some index files failed to download. They have been ignored, or old ones used instead.

... but it was immediately followed by a full list of packages and:

    Some packages could not be installed. This may mean that you have
    requested an impossible situation or if you are using the unstable
    distribution that some required packages have not yet been created
    or been moved out of Incoming.
    The following information may help to resolve the situation:

    The following packages have unmet dependencies:
     libldap2-dev : Depends: libldap-2.4-2 (= 2.4.28-1.1ubuntu4) but 2.4.28-1.1ubuntu4.4 is to be installed
     libsasl2-dev : Depends: libsasl2-modules (= 2.1.25.dfsg1-3) but 2.1.25.dfsg1-3ubuntu0.1 is to be installed
     sqlite3 : Depends: libsqlite3-0 (= 3.7.9-2ubuntu1) but 3.7.9-2ubuntu1.1 is to be installed
    E: Unable to correct problems, you have held broken packages.
