Subject: invalid file format generated for dependencies

Date: Tue, 22 Jan 2019 17:00:50 -0500

[Message part 1 (text/plain, inline)]

Package: sbuild
Version: 0.78.0-2
Severity: grave
Tags: upstream

Since the 0.78 upgrade, sbuild cannot build packages in jessie (and
maybe other suites). The build during the setup phase, while trying to
install the build-dependencies, with this error message:

W: Failed to fetch gzip:/var/lib/apt/lists/partial/_build_systemd-asEYMr_resolver-48eHqy_apt%5farchive_._Sources.gz Invalid file format

It looks like the Sources.gz generated for the build-dependencies
resolver is incorrectly formatted, which freaks out apt in the chroot.

This does not happen with sbuild 0.77.1-2. This seems to be a
regression introduced in this commit:

https://salsa.debian.org/debian/sbuild/commit/18f423619c176471d2adaafb7742cb204951a10c

... which was implemented to close bug #909847. In there, sbuild
reimplements dpkg-scanpackages and dpkg-scansources internally, but it
seems to do so incorrectly.

Attached are the build logs and the faulty Sources.gz files.

I have verified this is a regression from 0.77.1. I can also confirm
there is an easy fix, attached and forwarded.

Thanks to James Clark for the patch, described on #debian-devel. :)

Cheers,

I've got to design so you can put it together out of garbage cans. In
part because that's what I started from, but mostly because I don’t
trust the industrial structure—they might decide to suppress us
weirdos and try to deny us the parts we need.

Subject: [PATCH] fix syntax of generated Sources.gz files (Closes: #920227)

The rewrite of dpkg-scan* performed to fix #909847 introduced a
problem in 18f423619c176471d2adaafb7742cb204951a10c: Sources.gz
entries are not correctly separated by a newline. Furthermore, they
have Source: entries instead of Package:

This confuses older version of APT (previous to jessie) which have
extra sanity checks on the contents of those files, which breaks
building in older chroots.
