    Probles Signing *.deb Packages BADSIG _gpgbuilder

    I am running Ubuntu 12.04 and I am apparently having problems signing some packages and I am not sure why, others sign just fine.

    Here is an example of a package I need to sign, you can see from the commands below there is no signature on this package at all, then I sign it and the -s builder goes just fine; however when I try and verify the package I get the BADSIG _gpgbuilder.

    I have tried to create a new gpg key and still the same problem. I don't have this problem with all packages, some I've created work fine; however some I have created or found on the internet don't sign. I would guess the problem is with the package but I can install the packages just fine (if I don't use APT).

    Wouldn't it be better to contact Amazon about this problem?

    This has nothing to do with Amazon, while the server and the s3 bucket with this package is actually located in in S3 the issue exists with packages on my own Ubuntu desktop. When I sign some packages in this manner I have the same issue... so I am guessing I am doing something wrong here.

    I was having this same issue, and it was an existing bug: https://bugs.launchpad.net/ubuntu/+s...g/+bug/1156988

    Re: Probles Signing *.deb Packages BADSIG _gpgbuilder

    Hi,

    try the following:

    1. extract the content of the deb file using
    $ ar vx file.deb

    2. check the file _gpgbuilder and that the data file has an extension .tar.gz

    IF it has a .tar.xz means that the package was created using a dpkg-deb on Ubuntu which has default compress-type xz (check dpkg-deb's man page on option compress-type/-Z)

    dpkg-sig checks for data.tar.gz (as if the file was created with compress-type gzip - default behaviour on Debian).

    A small hack would be change the dpkg-sig Perl script to verify even if the data file has extension .tar.xz

    Hope it helps.

    Edit: someone made a nice patch http://osdir.com/ml/ubuntu-bugs/2014-07/msg09103.html
