[Bug 1689668] Re: dialog to resolve config file conflicts can be only one line high

[Brian Murray]

** Description changed:

  [Impact]
  The config file conflict dialog in update-manager will be only one line high. This essentially just shows the start of the diff making it hard for people to make an informed decision.
  
  [Test Case]
  1) Install artful (so you have updates to install)
  2) Modify /etc/update-manager/release-upgrades and set Prompt=never
- 3) Run update-manager (only install the new update-manager)
- 4) Observe the config file prompt dialog being 1 line high
+ 3) Edi /var/lib/dpkg/status and set the md5sum for /etc/update-manager/release-upgrades to something else e.g. use the md5sum for meta-release
+ 4) Run update-manager (only install the software updater group)
+ 5) Observe the config file prompt dialog being 1 line high
  
  With the version of aptdaemon from -proposed you will see multiple
  lines.
  
  [Regression Potential]
  Little - its a one line patch to to allow the dialog to expand vertically.
  
  Original Description
  --------------------
  
  This is similar to bug 1623856 regarding the download progress window
  only being one line high but the dialog affected is actually the one
  that says:
  
          title = _("Replace your changes in '%s' with a later version of "
                    "the configuration file?") % from_path
          msg = _("If you don't know why the file is there already, it is "
                  "usually safe to replace it.")
  
  I've observed this on Ubuntu 17.04 but suspect it also affects Ubuntu
  16.10 as the other bug does.
