[ debian-boot@ and apt-file@ people in x-d-cc. ]
Hi,
apt-file now relies on apt/apt-get indextargets to download/list
Contents files, and Contents-udeb-* files are missing at the moment.
Tracing this down into apt, it seemed GetIndexTargets needed a few
changes to get the proper filenames. AFAICT it's important to have both
MetaKey and ShortDesc to match reality, given the 4th parameter passed
to the Indextarget sets the URI based on the MetaKey, which is then used
to return the filename used in DoIndexTargets (cmdline/apt-get.cc).
I'm entirely unsure this is the right place/way to patch those things,
but that seems to work for all intents and purposes:
(sid-amd64-devel)kibi@wodi:~/hack/apt.git$ apt-file search efivars.ko|grep
-- -di:
efi-modules-4.5.0-2-amd64-di:
/lib/modules/4.5.0-2-amd64/kernel/drivers/firmware/efi/efivars.ko
I'm not sure about the following parts, but I suppose d-i is special
enough that people having “main/debian-installer” bits in their
sources.list shouldn't be too shocked by possible inconsistencies…
MetaKey: main/Contents-udeb-amd64

Subject: [PATCH] Add support for retrieving and listing Contents-udeb-* files.
Since apt-file now relies on apt-get indextargets to figure out which Contents
files to look for, it's important for apt to downloads Contents-udeb-* instead
of trying to download non-existing debian-installer/Contents-* files.
Rewrite MetaKey and ShortDesc accordingly, which enables apt-file to search into
udebs.
