Cannot install on ubuntu xenial

Original Redmine Issue: 14395
Affected QGIS version: 2.14.0
Redmine category:build/install

---

Using http://qgis.org/debian/ xenial repo (but also on debian-nightly) the installation of qgis 2.14 fails with this error:

dpkg: error processing archive /var/cache/apt/archives/qgis_1%3a2.14.0+24xenial_amd64.deb (--unpack):
trying to overwrite '/usr/bin/qgis.bin', which is the diverted version of '/usr/bin/qgis' (package: qgis-provider-grass)
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

I can provide more info if requested, but this is a pretty barebones installation of ubuntu xenial (ubuntugis is not installed).

And you don't have a stale diversion leftover from a previous installation (dpkg-divert --list | grep qgis)? Because the current package doesn't use diversions anymore and the above diversion should come from a nightly that dates back to the period where GRASS7 support was only in the provider, but not yet in the plugin - hence the diversion was moved from the plugin to the provider, later when GRASS7 support in the plugin appeared back to the plugin and finally completely removed.

$ dpkg-divert --list | grep qgis
diversion of /usr/bin/qbrowser to /usr/bin/qbrowser.bin by qgis-provider-grass
diversion of /usr/bin/qgis to /usr/bin/qgis.bin by qgis-provider-grass

qgis-provider-grass is 2.14.0

I had a previous install of qgis (wily version from ubuntu repos) but all of those packages were purged before trying to install the qgis.org debs.

Unfortunately purging doesn't help (current packages don't know qgis-provider-grass could have some - as said those only (intentionally) existed for a short period anyway).

Please just remove the diversions:

dpkg-divert --remove /usr/bin/qgis
dpkg-divert --remove /usr/bin/qbrowser

In #22281 Jürgen Fischer wrote:

should be fixed in 7489af8

The qgis.preinst only removes the diversion provided by qgis-plugin-grass, in 2.8 the diversions were provided by qgis-provider-grass and those are not removed.

This issue also affected the qgis package in Debian as reported in "Debian Bug #817176":https://bugs.debian.org/817176, there the upgrade is from 2.8.x which requires the diversion to also be removed for the qgis-provider-grass package.

For Debian I've changed qgis.preinst to remove the diversions for both qgis-plugin-grass and qgis-provider-grass with:

1. 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
