[buildd-tools-devel] Bug#817121: schroot: Failing lintian call via --run-session

[Mathias Behrle]

Package: schroot
Version: 1.7.2-3
Severity: normal

Dear Maintainer,

I am hit by this error with lintian failing when called in post build
chroot by sbuild. Not entirely sure if the assignment to schroot is
correct, but seems to me most adequate.

The relevant lines of the sbuild debug log:

...
D: Setting Dummy package path=undef
D: Setting Dummy archive directory=undef
D: Setting Dummy Release file=undef
I: schroot -d /<<BUILDDIR>> -c sid-amd64-sbuild-IgSZzA-3865 --run-session -q -u mathiasb -p -- lintian tryton-server_3.8.3-2_amd64.changes
D: Running command: schroot -d /<<BUILDDIR>> -c sid-amd64-sbuild-IgSZzA-3865 --run-session -q -u mathiasb -p -- lintian tryton-server_3.8.3-2_amd64.changes
tryton-server_3.8.3-2_amd64.changes is not available
D: Setting Lintian Reason=pass

D: Setting Lintian Reason=error
D: Setting Lintian Reason=fail
E: Lintian run failed (policy violation)
...

Basic information:
- I am using overlay in schroot conf
- I am aware of #798835 and running sbuild from experimental (0.68.0-1.0~exp1)

For debugging purposes I kept the chroot sessions available by running 
$ sbuild --purge=never -D

Indeed the command fails when calling lintian from outside the chroot:

mathiasb at monsterix:~/bin/tryton/debian_builder/tmp/tryton-server$
schroot -d /build/tryton-seriver-g23533 \
-c sid-amd64-sbuild-IgSZzA-3865 --run-session -q -u mathiasb \
-p -- lintian tryton-server_3.8.3-2_amd64.changes
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:

 are supported and installed on your system.
 perl: warning: Falling back to the standard
 locale ("C").
tryton-server_3.8.3-2_amd64.changes is not available

but succeeds with a call to ls:

mathiasb at monsterix:~/bin/tryton/debian_builder/tmp/tryton-server$
schroot -d /build/tryton-server-g23533 -c sid-amd64-sbuild-IgSZzA-3865 \
--run-session -q -u mathiasb -p -- ls
tryton-server-3.8.3  tryton-server-doc_3.8.3-2_all.deb
tryton-server_3.8.3-2.debian.tar.xz  tryton-server_3.8.3-2.dsc
tryton-server_3.8.3-2_all.deb  tryton-server_3.8.3-2_amd64.changes
tryton-server_3.8.3.orig.tar.gz

also the lintian call succeeds inside the chroot:

mathiasb at monsterix:~/bin/tryton/debian_builder/tmp/tryton-server$
schroot -r -c sid-amd64-sbuild-IgSZzA-3865
...
(sid-amd64-sbuild)mathiasb at monsterix:/$ cd build/tryton-server-g23533/
(sid-amd64-sbuild)mathiasb at monsterix:/build/tryton-server-g23533$

I am running out of ideas why especially the lintian command is failing
with schroot --run-session. Just now I am unable to reboot this machine,
but this will be one of the next steps to check. Please let me know what
I can do to track down further this issue.

Cheers,
Mathias
