Bug 786640

Do you still experience this problem with the current version? If you can reproduce, please run: 

$ abrt-gui -vvv

and send us the output.

This seems like a bug in yum. We use the yum API to download the packages like this:

current_pkg = 1
for pkg in package_list:
  print "Downloading %i of %i packages" % (current_pkg, len(package_list))
  self.downloadPkgs(pkglist=[pkg])
  current_pkg++

- and according to the log it looks like it's looping in the downloadPkgs() which comes from YumBase

Isn't the "print" statement above executed on each iteration, printing "Downloading 13 of 15 .." again and again?  downloadPkgs() might fail in some ways, but it very likely does not loop there.

- oops, sorry, the example is not correct, the message "Downloading .." comes from updateProgress callback which is called from the downloadPkgs()
- do the real code is:

<snip>
            err = self.downloadPkgs(pkglist=[pkg])
            # normalize the name
            # just str(pkg) doesn't work because it can have epoch
            pkg_nvra = pkg.name + "-" + pkg.version + "-" + pkg.release + "." + pkg.arch
            package_file_name = pkg_nvra + ".rpm"
            if err:
                # I observed a zero-length file left on error,
                # which prevents cleanup later. Fix it:
                try:
                    os.unlink(self.tmpdir + "/" + package_file_name)
                except:
                    pass
                print (_("Downloading package {0} failed").format(pkg))
            else:
                unpack_result = unpack_rpm(package_file_name, files, self.tmpdir,
                                           self.cachedir, self.keeprpms, exact_files=download_exact_files)
                if unpack_result == RETURN_FAILURE:
                    # recursively delete the temp dir on failure
                    print _("Unpacking failed, aborting download...")
                    clean_up()
                    return RETURN_FAILURE

            downloaded_pkgs += 1
</snip>

- and as you can see from the video the code after the line err = self.downloadPkgs(pkglist=[pkg]) is never reached (it should at least increase the downloaded_pkgs counter)

Yes, it's stuck in downloadPkgs().  My guess is it's not an infinite loop, downloader is just trying all mirrors (there are lots of them for F16) to download the remaining 5% of the 375MB file, but it keeps failing.  Ran out of space in /var/cache, perhaps?

    added error callback to get notification about download failure rhbz#786640

I added a notification for cases when downloading fails, so user knows what's going on and it doesn't look like it's restarting the download without any reason.
