I am running Lightburn under a floating licence on a Ubuntu 22.04 laptop.
I have downloaded the latest Linux Appimage (LightBurn-Linux64-v1.7.08.AppImage) and I am trying to follow the instructions to generate a license file by running the image as root
(sudo ,.AppImage -l [licence key])
It fails with this error message:
/tmp/.mount_LightBEPICOG/AppRun.wrapped: 13: Bad substitution
The characters after “Light” change randomly with each attempt.
I have tried deleting the ~/.config/Li ghtburn directory with no joy.
What next?
