[elbe-devel] [PATCH 3/3] rpcaptcache: use our own implementation of fetch_binary

[Torben Hohn]

in "elbe fetch_initvm_pkgs" Version.fetch_binary() produced an error:

------------------------------------------------------------------------------------------------------------------------------------------
Oct 20 07:39:21 in-target: Traceback (most recent call last):
Oct 20 07:39:21 in-target:   File "/bin/elbe", line 55, in <module>

Oct 20 07:39:21 in-target:   File "/usr/lib/python2.7/dist-packages/apt/package.py", line 867, in fetch_binary
Oct 20 07:39:21 in-target:     if _file_is_same(destfile, self.size, self._records.md5_hash):
Oct 20 07:39:21 in-target: SystemError: error return without exception set
------------------------------------------------------------------------------------------------------------------------------------------

The code there uses our own implementation of fetch_binary() which does
not try to access "_records.md5_hash". And there it works.

The same thing can also happen in rpcaptcache. So use our own versnion
there as well.
