_checkStoreConnectivity uses translatable strings for error checking

This bug was fixed in the package ubuntu-release-upgrader - 1:18.10.6

---------------
ubuntu-release-upgrader (1:18.10.6) cosmic; urgency=medium

  * DistUpgradeQuirks.py:
    - make sure that snapd is installed before trying to use it.
      (LP: #1783589)
    - update the view with information regarding the progress of snaps being
      installed. (LP: #1783593)
    - when checking for connectivity to the snap store use C.UTF-8 for the
      language so error message matching works. (LP: #1783738)
  * DistUpgradeController.py:
    - Remove debs from apt's "Dir::Cache::archives" folder after the upgrade
      has completed successfully.
    - Add a telemetry marker to report the time to process migration from deb
      to snaps.
  * DistUpgrade/DistUpgradeViewGtk3.py: call vte's terminal.feed_child() with
    the correct parameters thereby fixing a crash. (LP: #1780501)
