Failed to register AppImage in system via libappimage - how to fix?

This seems to be exclusive problem of only CubicSDR AppImage.

Three other AppImages like

  • App.Outlet-2.0.0-beta-1.AppImage
  • drawio-x86_64-14.6.13_fed376c2692af2074327a4f8fb9ccdf9.AppImage
  • ubports-installer_0.8.8-beta_linux_x86_64.AppImage
  • vnote-linux-x64.AppImage

are well integrated.

So I create a symlink between CubicSDR and my Desktop folder by

chmod +x ~/Software/AppImages/CubicSDR-0.2.5-x86_64.AppImage
ln -s ~/Software/AppImages/CubicSDR-0.2.5-x86_64.AppImage ~/Desktop/CubicSDR

and have reported issue to CubicSDR.
