[buildd-tools-devel] Bug#559655: sbuild: dealing with experimental is a PITA

[Cyril Brulebois]

Package: sbuild
Version: 0.59.0-1
Severity: important

Hi,

I tried to set up an sbuild chroot since cowbuilder was driving me nuts,
but it's not going much further. If apt-get is expected to behave badly,
sbuild probably should take that into account. If tweaks are expected in
the chroot (like apt pinning), that probably should be documented. And
since I couldn't find a single bug about experimental, I'm opening this
one.

My setup (forgetting the abspath issue for a second), assuming I
remember properly what I did a few hours ago:
| $ sudo sbuild-createchroot sid sid $mirror
| $ # rename appropriately
| $ # add experimental lines to sources.list
| $ sbuild-update experimental-amd64
| $ sbuild-upgrade experimental-amd64
| $ sbuild -c experimental-amd64-sbuild -s -A \
|     xserver-xorg-input-synaptics_1.2.0-3.dsc

(This version is available in experimental.)

First try:

| E: Broken packages
| apt-get failed.
| Package installation failed
| Trying to reinstall removed packages:
| Trying to uninstall newly installed packages:
| Source-dependencies not satisfied; skipping xserver-xorg-input-synaptics

So I decided to install xserver-xorg-dev from experimental manually in
the chroot, I'd be needing it anyway for multiple packages. Once that
done (sudo schroot + apt-get install --no-install-recommends), second
try:

| E: Broken packages

So I had to manually install (the same way) libxi-dev from experimental
before being able to actually build a single package (out of 30+).

It shouldn't be _that_ hard to build packages targeted at experimental.
As said above, I can understand some extra steps may be needed, but
please identify and document them (recursive grep on experimental in
sbuild's /u/s/d didn't reveal anything).

Thanks in advance.

Mraw,
KiBi.
