Package: apt
Version: 1.0.10.2
Severity: normal

Dear Maintainer,

If I run "apt-get update" (or "aptitude update") when the network is down (or
the proxy is unavailable), APT forgets everything instead of keeping using the
old data.

E.g. if I "Disconnect" the netowrk and run the following command:

    (export LANG=C; aptitude show emacs; apt-get update; aptitude show emacs)

I get something like:

    Package: emacs
    New: yes
    State: not installed
    Version: 46.1
    Priority: optional
    Section: editors
    Maintainer: Rob Browning <rlb@defaultvalue.org>
    Architecture: all
    Uncompressed Size: 25.6 k
    Depends: emacs24 | emacs24-lucid | emacs24-nox
    Description: GNU Emacs editor (metapackage)
     GNU Emacs is the extensible self-documenting text editor. This is a
metapackage
     that will always depend on the latest recommended Emacs release.

used instead.
    E: The value 'testing' is invalid for APT::Default-Release as such a

    E: The value 'testing' is invalid for APT::Default-Release as such a

Notice how the first "aptitude show" happily described the "emacs" package
before the update and couldn't do it any more after the update.  Instead I get
some bogus complaint about "testing" being an invalid setting for APT::Default-
Release.

Fixing this was an involved process happening over multiple months
resulting in a rewrite of the acquire system. If you feel like it you
can watch the DebConf15 talk "This APT has Super Cow Powers" where
I showed off some of the new features and explained some bits which are
otherwise likely to be missed as it just works. Otherwise, you can also
try to play with it yourself, its in experimental still for unrelated
reasons, but will be out of there 'shortly'. With that aptitude and co
will be fixed, too, automatically (they just have to be rebuilt, which
is one reason this takes some time, as we need a slot for this to
happen).

It depends a bit on the exact problem when it was fixed, but it its
between ~exp1 and ~exp13 – I pick the latest just because.
So closing as done.


Best regards
