I haven't been able to reproduce this issue with my piuparts setup, not now and not before, I guess piuparts.d.o. does something more complicated than: piuparts -d jessie -d stretch -a qgis I have now been able reproduce this issue manually in a jessie cowbuilder chroot by installing qgis (with recommended dependencies), and upgrading it to stretch via the usual procedure (apt-get upgrade followed by apt-get dist-upgrade). > I'll try to find some time to look there myself. > > Preparing to unpack .../qgis_2.14.6+dfsg-3_amd64.deb ... > Unpacking qgis (2.14.6+dfsg-3) over (2.4.0-1+b1) ... > dpkg: error processing archive > /var/cache/apt/archives/qgis_2.14.6+dfsg-3_amd64.deb (--unpack): >trying to overwrite '/usr/bin/qbrowser.bin', which is the diverted version > of '/usr/bin/qbrowser' (package: qgis-plugin-grass) Do you have a more complete log than the above? piuparts.debian.org/jessie2stretch still reports: successfully-tested 2.14.5+dfsg-2 Since the unpack is already failing, I think the diversion should also be removed by the maintainer scripts for qgis-plugin-grass, not just qgis as it is now. I suspect the complete log to confirm that qgis-plugin-grass is upgraded before qgis is, that's what I'm seeing in my jessie to stretch upgrade. Some testing of the above reveals that adding the maintainers scripts to qgis-plugin-grass to remove the diversion is not sufficient. The jessie version of qgis-plugin-grass only removes the diversion in postrm which is called after the new package's files are unpacked which is too late because the unpackaging causes the error. I think the jessie version of qgis needs to be fixed to remove the diversion in qgis-plugin-grass.prerm too, because a version of the package is already "Installed". Because the qgis-plugin-grass package is being upgraded, the new preinst could also remove the diversions before the new package's files are unpacked. But unfortunately that fails with: dpkg-divert: error: rename involves overwriting `/usr/bin/qgis.bin' with different file `/usr/bin/qgis', not allowed Just removing without renaming in qgis.preinst could be the actual solution, it seems to give the desired results: Preparing to unpack .../qgis_2.14.6+dfsg-4_amd64.deb ... Removing 'diversion of /usr/bin/qgis to /usr/bin/qgis.bin by qgis-plugin-grass' Removing 'diversion of /usr/bin/qbrowser to /usr/bin/qbrowser.bin by qgis-plugin-grass' Unpacking qgis (2.14.6+dfsg-4) over (2.4.0-1+b1) ... It's a much simpler change in addition to the one fixing #817176, I should have thought of that sooner before you led me astray with your suggestions in this issue. I'm going to upload the above which should finally fix this issue.

And a lovely mess it has created now that we don't need it any more. The situation is complicated by the fact that upstream moved the diversion around in non-LTRs which were never in Debian. Fortunately we don't have to care about the upstream use-case in Debian. The jessie version (2.4.0-1) added the diversion in qgis-plugin-grass.preinst: if [ "$1" = "install" -o "$1" = "upgrade" ]; then dpkg-divert --package qgis-plugin-grass --add --rename \ --divert /usr/bin/qgis.bin /usr/bin/qgis dpkg-divert --package qgis-plugin-grass --add --rename \ --divert /usr/bin/qbrowser.bin /usr/bin/qbrowser fi And removed it qgis-plugin-grass.postrm: if [ "$1" = "remove" ]; then dpkg-divert --package qgis-plugin-grass --remove --rename \ --divert /usr/bin/qgis.bin /usr/bin/qgis dpkg-divert --package qgis-plugin-grass --remove --rename \ --divert /usr/bin/qbrowser.bin /usr/bin/qbrowser fi The sid version (2.14.6+dfsg-1) just removed it in qgis.preinst: if [ "$1" = "install" -o "$1" = "upgrade" ]; then # Remove obsolete diversions for i in /usr/bin/qgis /usr/bin/qbrowser; do pkg=$(dpkg-divert --listpackage $i) if [ -n "$pkg" -a "$pkg" = qgis-plugin-grass -o \ "$pkg" = qgis-provider-grass ]; then dpkg-divert --package $pkg --rename --remove $i fi done fi The above has been moved in -2 to postinst, which doesn't get called with the install or upgrade arguments, which I've not fixed by checking for the configure argument. It seems the underlaying issue was not removing the diversion in prerm as well, I've now added that too. If that is still not sufficient to fix this issue, I guess we need the removals in qgis-plugin-grass package too.
