Alright, but at least we have a partial success =)  The GUI then should
start by running:

  sudo flatpak run --branch=stable org.octave.Octave --gui

Now we are facing a bunch of problems related to the sudo starts, which
need to be addressed one by one in the given order:

1) Uninstall Octave flatpak
2) Remove the folder "/home/edumapurunga/.config/octave/", which now
probably belongs to root and should cleanly be recreated the next time.
3a) Remove any folders
"/run/ld-so-cache-dir/b5e9492c806c540a564b49a202dfca5af252935f7f736d47519d5c6968526faf"
which as normal user you do not have permission to
3b) Maybe consider a clean system reboot
4) Install Octave flatpak and start is WITHOUT SUDO privileges

HTH,
Kai
