Bug#358320: apt: apt-get update while offline deletes downloaded indices

[Daniel Schepler <schepler@math.berkeley.edu>]

Package: apt
Version: 0.6.43.3
Severity: important

I have a setup with both an http URL from a Debian mirror, and file URL's from 
a local repository, in /etc/apt/sources.list.  While I'm offline, it often 
happens that I put new packages in the local repository and want to upgrade 
to the new versions.  However, when I run apt-get update without network 
access, the index files previously downloaded from the Debian mirror get 
completely deleted, which is very annoying.

If you have trouble reproducing this, let me know and I can send the 
sources.list, preferences, and/or Packages,Release from the local repository 
on my setup.
