Tags: pending Thank you for your bug report! I have addressed this in the new version 1.6.1-2 which is not uploaded yet.
As Salsa CI tests passed successfully (including piuparts) here are the steps to reproduce this locally (mostly as a note to myself): At the moment purging fails in piuparts because of leftovers from fontconfig (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=897040) and something related to systemd (no bug number found): 6m4.7s ERROR: FAIL: Package purging left files on system: /etc/systemd/user/ owned by: systemd /usr/local/share/fonts/ not owned /usr/local/share/fonts/.uuid not owned /usr/share/fonts/ owned by: fonts-opensymbol, fonts-dejavu-core /usr/share/fonts/.uuid not owned /usr/share/fonts/truetype/ owned by: fonts-opensymbol, fonts-dejavu-core /usr/share/fonts/truetype/.uuid not owned /usr/share/fonts/truetype/dejavu/ owned by: fonts-dejavu-core /usr/share/fonts/truetype/dejavu/.uuid not owned /usr/share/fonts/truetype/openoffice/ owned by: fonts-opensymbol /usr/share/fonts/truetype/openoffice/.uuid not owned /var/lib/systemd/deb-systemd-user-helper-masked/ not owned For now using option --warn-on-leftovers-after-purge. $ sudo piuparts --warn-on-leftovers-after-purge -d testing parlatype_1.6.1-1_amd64.changes # buggy version dpkg: error processing archive /tmp/apt-dpkg-install-ysSQvu/0-libparlatype2_1.6.1-1_amd64.deb (--unpack): trying to overwrite '/usr/share/locale/ca/LC_MESSAGES/libparlatype.mo', which is also in package libparlatype1:amd64 1.5.6-1 $ sudo piuparts --warn-on-leftovers-after-purge -d testing parlatype_1.6.1-2_amd64.changes # new version 9m28.0s INFO: PASS: Installation, upgrade and purging tests.
