Bug#807487: pbuilder update in sid breaks pbuilder on (old)stable

[Holger Levsen]

package: pbuilder
version: 0.221.2
severity: grave

Hi Mattia,

from #debian-qa:

<h01ger> | anybody knows why sid is broken as in https://reproducible.debian.net/rbuild/unstable/armhf/pianobar_2015.11.22-1.rbuild.log ?
<h01ger> | tail: cannot open 'debian/changelog' for reading: No such file or directory
<h01ger> | dpkg-buildpackage: error: tail of debian/changelog gave error exit status 1
<jwilk> That's bizarre.
<h01ger> | jwilk: yup. and we only see it for sid, not for testing, so it has to be some change in sid…
<jwilk> Is it only armhf?
<h01ger> | no. also amd64
<lamby> cd /build/*/ # you sure there's nothing else in there?
<lamby> I do so a mention of /build/.gnupg a few lines up which, of course, should not expand by default..
<h01ger> | its created by pbuilder… as this happens inside the chroot created by it 
<h01ger> | but 
<h01ger> | only pbuilder in sid has been updated
<h01ger> | not on the host
<h01ger> | but we had such a bug before
<h01ger> | pbuilder-0.221.2/pbuilder-buildpackage:    DPKG_COMMANDLINE="cd ${BUILDDIR}/*/ && $DPKG_COMMANDLINE"
<h01ger> | lamby: so thats from pbuilder indeed
<h01ger> | i dont grok how pbuilder in sid effects building using pbuilder in stable, but i think the pbuilder upgrade is the cause 
<h01ger> | and fwiw, i can reproduce it here, using pbuilder 0.213 on wheezy ;-p

IOW: when trying to build packages for sid on this oldstable system using
pbuilder 0.213 I see the exact same behaviour as in 
https://reproducible.debian.net/rbuild/unstable/armhf/pianobar_2015.11.22-1.rbuild.log
which is:

I: Building the package
I: Running cd tmp/buildd/*/ && env PATH="/usr/sbin:/usr/bin:/sbin:/bin" dpkg-buildpacka
tail: cannot open 'debian/changelog' for reading: No such file or directory
dpkg-buildpackage: error: tail of debian/changelog gave error exit status 1
E: Failed autobuilding of package

As shown on reproducible.debian.net this doesn't effect building for testing.


cheers,
	Holger
