On Ubuntu 18.04.3, installed via the ppa repository. I've had this happen three times now. I run blocksat gui the first time to get my satellite aligned, then I shut it down by clicking X in upper right corner of the gui. Next time I attempt to run it, I get the following error. I have to uninstall the satellite repository and reinstall it. It will again launch ok first time, then after stopping the gui it won't launch again.
