    apt package list problem - corrupted/lost apt package list file

    It seems the last time I was in a wifi 'hotspot' zone, ubuntu decided to update package lists, and overwrote one of the package list files with the html response from the wifi proxy....

    Which means this file:
    /var/lib/apt/lists/gb.archive.ubuntu.com_ubuntu_dists_natty_restricte d_binary-amd64_Packages

    ..is now corrupted and unusable.

    I have tried to clean and update:

    apt-get check
    apt-get clean
    apt-get update

    no joy.

    Where can I download this file manually? Or is there a way to fix this automatically?

    Cheers

    Hi, first open terminal type
    sudo dpkg --configure -a then
    sudo apt-get update and that should fix the problem.

    Thanks for the response.

    Tried this, though unfortunately still no joy... Exact error message when running sudo apt-get update is:

    Code:
    Reading package lists... Error!
    E: Encountered a section with no Package: header
    E: Problem with MergeList /var/lib/apt/lists/gb.archive.ubuntu.com_ubuntu_dists_natty_restricted_binary-amd64_Packages
    E: The package lists or status file could not be parsed or opened.
    Essentially this happened when the file was corrupted (contained the proxy web page html), when the file was missing (I deleted it) and with an empty file.

    I've tried installing a VM with a fresh install of Ubuntu to get a copy of that file.. though it was empty, so I guess this way will require me to install a similar set of apps/etc to get a working file... which isn't very practical.

    Any other suggestions? surely I should be able to rebuild this list somehow?

    OK.. looks like I've fixed it.

    Sigh... in my haste I missed that the error after I removed the erroneous file was for a different file... the names looked so similar at first glance that I thought they were the same.

    So, the simple fix was to delete the erroneous files in /var/lib/apt/lists/ (it was actually most of the files in that directory), and run apt-get update.

    Thank you for the tip.
    I have no proxy, so don't know how it happened. I just got back from a weeks trip and it was like that.
    I just remove everything in the lists dir and then the update started working again. Natty 64bits here.
