The main reason I haven't touched those bugs is that there are many
more important things to work on. This behavior might be annoying when
it hits you, but the files that are wiped out are all cache files that
you can download from the network when your connection is re-established.
A secondary reason is that I can't figure out what's going on, because
whenever I try taking my network down and running an update, my package
lists are still around afterwards. I've read over the code and it looks
to me like it only deletes the old package lists when it successfully
downloaded new ones. Until I get more of a clue to go on, this looks to
me like a way to waste a great deal of time.
I put the apt-get and aptitude code up side-by-side and I can only see
one difference in the conditions they use to determine whether to clean
the lists. I don't see why this would matter (surely pkgAcquire::Run
returns Failure if files can't be downloaded?), but if there's anyone
who *can* reproduce this on demand, it would be interesting to know if
the attached patch helps.
