[GNC] AqBanking Wizard won't start

[Peter Dutton]

   I'm trying to get the Aqbanking wizard to run.  While in GC v 3.11 I
   clicking on Start AqBanking Wizard (button) does nothing.  I installed
   Flatpak which had no effect so far.  Not sure how to use flatpak.

   I'm running- Ubuntu 18.04 Mate

   Thanks,

   Peter
