Bug Description

When upgrading a system from eoan to focal, I opened the terminal within the release upgrader because I like to watch the progress of the package installations. To my surprise, a debconf prompt popped up in the terminal.

update-manager should always be running in a configuration that uses the gnome frontend, and the release upgrader should be inheriting this setting.

The libgtk3-perl package is installed. However, the environment passed to dpkg shows DEBIAN_FRONTEND=dialog is set instead.

Found in ./DistUpgradeViewGtk3.py:

        if frontend == "gnome" and self._cache:
            if (not "libgtk2-perl" in self._cache or
                not self._cache["libgtk2-perl"].is_installed):

        if "DEBIAN_FRONTEND" not in os.environ:
            self.env.append("DEBIAN_FRONTEND=%s" % frontend)

libgtk2-perl is obsolete and no longer installed by default on the desktop. This needs updated for libgtk3-perl.

This bug was fixed in the package ubuntu-release-upgrader - 1:20.04.18

---------------
ubuntu-release-upgrader (1:20.04.18) focal; urgency=medium

  [ Steve Langasek ]
  * Use libgtk3-perl, not libgtk2-perl, to decide whether to use the gnome
    debconf frontend; debconf migrated to GTK+3 in version 1.5.66, before
    bionic was released. LP: #1871530.

  [ Brian Murray ]
  * data/mirrors.cfg, utils/update_mirrors.py: Add in ddebs.ubuntu.com as an
    official package source.
