[Piuparts-devel] Bug#1137591: piuparts: Problem removing link autovt at .service causing false positive outcome

[Tommi Höynälänmaa]

Package: piuparts
Version: 1.6.0
Severity: important
X-Debbugs-Cc: tommi.hoynalanmaa at iki.fi

Dear Maintainer,

Piuparts has been starting to give false positive outcome for
several packages. Piuparts worked with g-golf before but now it gives
an error with package g-golf-gtk-4-examples_0.8.7-3_all.deb.
The error occurs in the removal of the packages. The error is:
---cut here---
1m47.2s ERROR: FAIL: Package purging left files on system:
  /etc/systemd/system/autovt at .service -> /usr/lib/systemd/system/getty at .service not owned

1m47.2s ERROR: FAIL: After purging files have been modified:
  /	 not owned

1m47.2s ERROR: FAIL: Installation and purging test.
---cut here---

Steps to reproduce the error:
1. Install git-buildpackage and sbuild if you don't have them already.
2. If you have package g-golf installed to your system uninstall it.
3. Create a new work directory and cd into it.
4. Create file build.sh with the following contents:
---cut here---
#!/bin/sh

sbuild -s -d unstable --source-only-changes \
       --run-lintian \
       --lintian-opt=-I --lintian-opt=--pedantic $*
---cut here---
5. Run the following commands:
---cut here---
chmod +x build.sh
sudo apt-get build-dep g-golf
mkdir build-area
gbp clone https://salsa.debian.org/tohoyn-guest/g-golf.git
cd g-golf
gbp buildpackage --git-builder=$(pwd)/../build.sh
cd ../build-area
sudo piuparts --shell-on-error g-golf-gtk-4-examples_0.8.7-3_all.deb
dpkg -S /etc/systemd/system/autovt at .service
ls -l /etc/systemd/system/autovt at .service
readlink -f /etc/systemd/system/autovt at .service
exit
---cut here---

Expected results: The piuparts tests should pass.

Actual results: Piuparts reports the error described before.
Commands in point 4 show that /etc/systemd/system/autovt at .service
is not owned by any package but it is present in the system.

This bug has been reproduced in an up-to-date Debian unstable environment.
